PSI-K REPORT OF THE CHAIRMAN YEAR ENDED 31 DECEMBER 2023

In 2023, the Psi-k Charity supported a diverse and stimulating scientific and educational programme of 25 workshops, summer schools and hands-on tutorials, the list of which can be found at https://psi-k.net/psi-kworkshops/. Among these were: the major annual research conference supported jointly with CECAM, the European Centre for Atomic and Molecular Calculations (CECAM), on the topic of Bridging length scales with machine learning: from wavefunctions to thermodynamics (https://sites.google.com/view/cecam-psik2023/home); schools and tutorials aimed specifically at training graduate students and early career researchers in state-of-the-art methods in computational materials science and related subjects, including the Young Researchers’ School on Theory and Simulation in Electrochemical Conversion Processes (https://www.cecam.org/workshop-details/1216), and the School on Machine Learning Interatomic Potentials (https://www.cecam.org/workshop-details/1213); and the first event that we have supported in India, New approaches and machine learning methods for ab initio calculations (https://nammapsik.iisc.ac.in).

One Psi-k Highlight was published in October on “CELL: a Python package for cluster expansion with a focus on complex alloys” by Santiago Rigamonti, Maria Troppenz, Martin Kuban, Axel Huebner, and Claudia Draxl, and can be found at https://psi-k.net/highlights/, together with all those published from 1994 onwards. The Highlight series showcases work that combines breadth and depth and is relevant to the Psi-k community. Suggested contributions can be discussed with leon.petit@stfc.ac.uk. We have established informal agreements with journals including npj Computational Materials and IOP Electronic Structure that provide opportunities for open-access publication of Psi-k Highlights.

We continue to be inspired by the generous donations by groups worldwide, which enable Psi-k’s rich programme of activities. In 2023, 25 groups or institutions from 12 countries contributed to the charity. Anyone (individuals, groups, organisations, companies) who would like to contribute may contact a.mostofi@imperial.ac.uk and PSIK_ADMIN@stfc.ac.uk, or contribute directly using PayPal via the link at https://psi-k.net.

2023 has also seen a full refresh of PSI-K’s Working Groups, which were last reorganised in 2017. This refresh was informed both by the topical distribution of abstracts in the 2022 Psi-k Conference in Lausanne, and through direct community engagement. It has resulted in a total of 22 Working Groups (up from 16 previously), organised by four main themes (up from three previously), each overseen by at least one Trustee (named in parenthesis):

In addition to the scientific topics covered in themes A to C, the new theme D includes Working Groups dedicated to social responsibility, early career researchers, industry engagement, training and education, and policy engagement. As of the end of 2023, the membership of the Working Groups is being finalised to be ready for the 2024 cycle of proposals for activities. Further information about the Working Groups can be found at https://psi-k.net/groups/.

The Working Groups are instrumental in soliciting proposals for activities from the community, and assisting Trustees in evaluating proposals submitted in a two-step process: there is a first deadline at the end of July for outline proposals; these are evaluated and either encouraged to submit a full proposal by the end of October, rejected right away, or advised to merge with other efforts on similar themes to avoid duplication. The Psi-k/CECAM Research Conference has a separate track, and proposals not selected but deemed of sufficient quality can directly apply as a full proposal.

PSI-K REPORT OF THE CHAIRMAN (Continued) YEAR ENDED 31 DECEMBER 2023

The Board of Trustees met five times in 2023, all by teleconference: on 17 February, 21 April, 23 June, 15 September and 3 November. Minutes of meetings are recorded, circulated, and kept for internal use. The Trustees (https://psi-k.net/admin/), plus Working Group leaders (https://psi-k.net/groups/) and members of the Scientific Advisory Committee (https://psi-k.net/scientific-advisory-committee/) attended the Annual Meeting on 24 November, where all activities are finalised for the following year (in this case, from April 2024 to March 2025).

The generous contribution of time from all the groups above is essential to the wellbeing of the charity, but particular thanks must go to our Operations Manager, Damian Jones, (STFC Daresbury Laboratory, UK) for coordinating all the administration; to Igor Abrikosov and Nicola Marzari, who stepped down as a Trustees at the end of 2023, having served for 10 and 12 years, respectively; and to Peter Haynes who stepped down as Psi-k Chair, having served his three-year tenure, and who remains a Trustee and will Chair the next Psi-k Conference in 2025.

PSI-K REPORT OF THE TRUSTEES YEAR ENDED 31 DECEMBER 2023

The Trustees present their annual report and unaudited financial Statements for the year ended 31 December 2023.

Trustees

The Trustees who served during the period and to the date of this report were: Igor Abrikosov Silke Biermann Stefan Blügel Claudia Draxl Martin Friak Peter Haynes (resigned as Chair) Nicola Marzari Angelos Michaelides Elisa Molinari Arash Mostofi (appointed as Chair) Lucia Reining

The Trustee whose name are starred (*) resigned following the Annual Meeting on 24 November 2023.

Structure, governance and management

The organisation is governed by its Memorandum and Articles of Association and is a registered company limited by guarantee.

Psi- k is a Europe-based, worldwide network of researchers working on the advancement of first-principles computational materials science. Its mission is to develop fundamental theory, algorithms, and computer codes in order to understand, predict, and design materials properties and functions. Theoretical condensed matter physics, quantum chemistry, thermodynamics, and statistical mechanics form its scientific core. Applications encompass inorganic, organic and bio-materials, and cover a whole range of diverse scientific, engineering, and industrial endeavours. Key activities of Psi-k are the organisation of conferences, workshops, tutorials and training schools as well as the dissemination of scientific thinking in society.

Psi-k has a minimum of three Trustees, but there is no maximum. On the date of this report there were nine Trustees.

Psi-k has a Chair, and a Scientific Advisory Committee (SAC) of about 80 members, which is headed by the Chair of Psi-k. In addition all Trustees are also SAC members.

The Board of Trustees meets on average five to six times a year, normally with a combination of face-to-face meetings and teleconference meetings. In 2023 there were five meetings, all by teleconference: on 17 February, 21 April, 23 June, 15 September and 3 November. The Trustees had the opportunity to meet in person at the Annual Meeting of the SAC on 24 November. Minutes of meetings are recorded, circulated, and kept for internal use. The Board of Trustees uses these meetings to discuss matters including but not limited to: future strategy, funding and finances, events such as workshops, conferences and summer schools, and relationships with external organisations such as CECAM.

The day to day running of Psi-k is delegated to the Chair, Peter Haynes, who resigned with effect from 31 December but remains a Trustee. The Chair from 1 Jan 2024 is Arash Mostofi. The Chair is supported by the Operations Manager, Damian Jones.

The SAC meets once a year, normally in November, together with the leaders of the 16 Working Groups (https://psi-k.net/groups/). It is chaired by the Chair of Psi-k and its role is to make recommendations to the Board of Trustees, particularly regarding plans for all activities for the following year (in this case, from April 2024 to March 2025). In 2023 the Annual Meeting was held on 24 November in hybrid mode: in person in Paris and online.

These unaudited financial statements have been subjected to independent examination. See report on page 8.

PSI-K REPORT OF THE TRUSTEES (Continued) YEAR ENDED 31 DECEMBER 2023

All Trustees gave their time freely and no Trustee remuneration was paid in the year: expenses paid to Trustees amounted to €nil. Trustees are required to disclose all relevant interests and register them with the Chair.

Trustees are required to declare any conflicts of interest at each meeting and these are recorded in the minutes. If a vote of the Trustees is required on a matter, a Trustee who has declared a conflict of interest on that matter may not cast a vote.

Risk management

The Trustees have considered the major risks to which the charity is exposed and have reviewed those risks and established systems and procedures to manage those risks.

A significant risk for the Psi-k Charity is reduced financial funding. Since 2016, Psi-k has been sustained entirely by donations. In 2021 the Trustees agreed that our annual expenditure on community activities is determined by our income from the previous year, and adopted a target for reserves of €200,000.

Objectives and activities

Europe has become the leading research area in the world for the application of first-principles computational modelling to materials science and Psi-k aims to maintain and enhance this status.

“Psi-k research” covers structures, properties and processes in all types of materials at the atomic level and in nanometre-scale structures, studied by ab initio quantum-mechanical computer simulation. A series of working groups represent the views of the community and organise activities to deliver the Psi-k mission. During 2023 these were refreshed to reflect current trends in the discipline and to expand their scope with the creation of a new Theme D:

Theme A: Physical Formalisms:Ground State and Spectroscopy of Many-Electron Systems Theme A: Physical Formalisms:Ground State and Spectroscopy of Many-Electron Systems

PSI-K REPORT OF THE TRUSTEES (Continued) YEAR ENDED 31 DECEMBER 2023

Psi- k will promote and coordinate collaboration within the European research community by, among others, the following measures:

The activities are open to all researchers in the field. Psi-k acts as a vehicle to engaging with the wider scientific community, with industry, European policy makers and trans-European computer centres. It will seek to maintain cooperation with organisations such as the Centre Européen de Calcul Atomique et Moléculaire (CECAM), the European molecular simulation community and its networks and Psi-k’s counterpart research communities on other continents.

Aims and objectives for 2023

The main activities planned during 2023 comprised the scientific programme of workshops, tutorials and summer schools on the electronic structure of complex processes in materials, i.e. the topic of the Psi-k Charity. The programme comprised 25 events, including the major annual research conference supported jointly with CECAM, the European Centre for Atomic and Molecular Calculations (CECAM), on the topic of “Bridging length scales with machine learning: from wavefunctions to thermodynamics” (https://sites.google.com/view/cecam-psik-2023/home).

Grant making policy

The Psi-k Charity does not make grants to other research bodies. Generally, grant payments are made to institutions regarding scientific conferences.

The Psi-k Charity applies its funding to the organization of workshops, summer schools, hands-on courses and the Psi-k Conference. The Theoretical and Computational Physics Group at STFC Daresbury Laboratory publishes the Psi-k Newsletter and provides administrative support.

The achievements of every workshop to which Psi-k contributes are monitored in the form of a report which is published on the Psi-k website (http://psi-k.net/).

Key performance indicators

In 2023 the Psi-k Charity organised 25 workshops, conferences and training activities, which is in the middle of the typical range of 20 to 25 events and activities that have been supported in previous years.

Financial review 2023 and plan for 2024

Unrestricted net expenditure for the year was (€42,829) (2022: net income of €75.976). Unrestricted retained funds at the year end were €372,102 (2022: €414,931).

Member donations in 2023 amounted to a total of about €100,000 received. The expenses in the 2023 budget included €120,000 for workshops.

Plan for 2024: The Trustees continue to seek new contributors with an aim of increasing annual donations to around €150,000. The amount of €121,000 will be spent for workshops in 2024. Any deficit will be covered by the reserves.

During the year 2023 the Trustees were satisfied that, as far as circumstances permitted, the Charity continued to benefit the public through its activities targeted to achieve its charitable objectives.

Public Benefit

The Trustees confirm that they have referred to the guidance contained in the Charity Commission’s general guidance on public benefit when reviewing the Trust’s aims and objectives and in planning future activities and setting the grant making policy for the year.

INDEPENDENT EXAMINER’S REPORT TO THE TRUSTEES OF PSI-K

I report to the trustees on my examination of the financial statements of PSI-K (“the company”) for the year ended 31 December 2023, which are set out on pages 9 to 16.

Responsibilities and basis of report

As the trustees of the company (and also its directors for the purposes of company law) you are responsible for the preparation of the financial statements in accordance with the requirements of the Companies Act 2006 (‘the 2006 Act’).

Having satisfied myself that the financial statements of the company are not required to be audited under Part 16 of the 2006 Act and are eligible for independent examination I report in respect of my examination of your charity’s financial statements as carried out under section 145 of the Charities Act 2011 (‘the 2011 Act’). In carrying out my examination I have followed the Directions given by the Charity Commission under section 145 (5)(b) of the 2011 Act.

An independent examination does not involve gathering all the evidence that would be required in an audit and consequently does not cover all the matters that an auditor considers in giving their opinion on the financial statements. The planning and conduct of an audit goes beyond the limited assurance that an independent examination can provide. Consequently, I express no opinion as to whether the financial statements present a ‘true and fair view’ and my report is limited to those specific matters set out in the independent examiner’s statement.

Independent examiner’s statement

I have completed my examination. I confirm that no material matters have come to my attention in connection with the examination giving me reasonable cause to believe that in any material respect:

  1. accounting records were not kept in respect of the company as required by section 386 of the 2006 Act; or

  2. the financial statements do not accord with those records; or

  3. the financial statements do not comply with the accounting requirements of section 396 of the 2006 Act other than any requirement that the financial statements give a ‘true and fair view’ which is not a matter considered as part of an independent examination; or

  4. the financial statements have not been prepared in accordance with the methods and principles of the Statement of Recommended Practice: Accounting and Reporting by Charities applicable to charities preparing their financial statements in accordance with the Financial Reporting Standard applicable in the UK and Ireland (FRS 102).

I have no concerns and have come across no other matters in connection with the examination to which attention should be drawn in this report in order to enable a proper understanding of the financial statements to be reached.

PSI-K NOTES TO THE FINANCIAL STATEMENTS YEAR ENDED 31 DECEMBER 2023

1. ACCOUNTING POLICIES

a. Basis of preparation

The financial statements have been prepared in accordance with Accounting and Reporting by Charities: Statement of Recommended Practice applicable to charities preparing their financial statements in accordance with the Financial Reporting Standard applicable in the UK and Republic of Ireland (FRS 102) (Issued October 2019) - (Charities SORP (FRS 102)), the Financial Reporting Standard applicable in the UK and Republic of Ireland (FRS 102) and the Companies Act 2006.

The financial statements are prepared in Euro and amounts in these financial statements are rounded to the nearest Euro.

PSI-K meets the definition of a public benefit entity under FRS 102. Assets and liabilities are initially recognised at historical cost or transaction value unless otherwise stated in the relevant accounting policy notes.

b. Preparation of the financial statements on a going concern basis

The trustees forecast that the charity will continue to be able to pay its liabilities as they fall due for a period of at least 12 months following the date of approving the financial statements. The forecasts take into account transactions that are anticipated to take place in the foreseeable future and indicate that no additional financial resources will be required should the actual performance differ from forecast. On this basis the trustees have concluded that adopting the going concern basis of accounting in preparing the annual financial statements is appropriate.

c.

Income recognition

Incoming resources represents donations from research bodies in Europe to support the company’s activities, less amounts carried forward to future periods as deferred income; and donated services, which are included based on the hours worked and the appropriate hourly rate. Income is recognised when the entity has entitlement to the funds, it is probable that the income will be received and the amount can be measured reliably.

d. Donated services

Donated services are included within incoming resources with an equivalent amount shown within resources expended, where the benefit to the charity is reasonably quantifiable, measurable and material. The value placed on these resources is the estimated value to the charity of the service received.

e.

Deferred income

Donations received in advance of the period that they relate to, or which are provided specifically for future periods, are carried forward as deferred income. These amounts relate to contributions from research bodies received in advance.

f. Expenditure recognition

All expenditure is accounted for on an accruals basis, inclusive of any VAT which cannot be recovered.

Grants payable are payments made to third parties in the furtherance of the charitable objectives of the Charity. Grants are accounted for when either the recipient has a reasonable expectation that they will receive a grant and the trustees have agreed to pay the grant without condition, or the recipient has a reasonable expectation that they will receive a grant and any condition attaching to the grant is outside of the control of the Charity.

Provisions for grants are made when the intention to make a grant has been communicated to the recipient but there is uncertainty about either the timing of the grant or the amount of grant payable.

Governance costs are related to the governance of the charity, such as the costs of preparing the financial statements and statutory compliance.

Irrecoverable VAT is charged as a cost against the activity for which the expenditure was incurred.

These unaudited financial statements have been subjected to independent examination. See report on page 8.

Page 11

PSI-K NOTES TO THE FINANCIAL STATEMENTS YEAR ENDED 31 DECEMBER 2023

1. ACCOUNTING POLICIES (Continued)

g. Charitable Funds

Restricted funds are to be used for specified purposes as laid down by the donor. Expenditure which meets these criteria is identified to the fund, together with a fair allocation of management and support costs.

Unrestricted funds are available for use at the discretion of the Trustees in furtherance of the general objectives of the Charity.

h. Foreign currencies

The trustees consider that the functional currency of the charity is the Euro, as most transactions are denominated and are carried out in that currency.

Assets and liabilities denominated in other currencies are translated into Euros at the rate of exchange ruling at the balance sheet date. Transactions in other currencies are translated into Euros at the rate of exchange ruling at the date of the transaction. Exchange differences are taken into account in arriving at the net movement in funds in the Statement of Financial Activities.

At the balance sheet date the rate of exchange between Sterling and Euro was £1 equals €1.1505 (2022: €1.1295).

i. Financial instruments

The Charity has elected to apply the provisions of Section 11 ‘Basic Financial Instruments’ and Section 12 ‘Other Financial Instruments Issues’ of FRS 102, in full, to all of its financial instruments.

Financial assets and financial liabilities are recognised when the Charity becomes a party to the contractual provisions of the instrument, and are offset only when the Charity currently has a legally enforceable right to set off the recognised amounts and intends either to settle on a net basis, or to realise the asset and settle the liability simultaneously.

j. Basic Financial assets

Trade and other debtors (including accrued income) which are receivable within one year and which do not constitute a financing transaction are initially measured at the transaction price and subsequently measured at amortised cost, being the transaction price less any amounts settled and any impairment losses.

k. Basic Financial liabilities

Financial instruments are classified as liabilities according to the substance of the contractual arrangements entered into.

Trade and other creditors (including accruals) payable within one year that do not constitute a financing transaction are initially measured at the transaction price and subsequently measured at amortised cost, being the transaction price less any amounts settled.

l.

Derecognition of financial liabilities

Financial liabilities are derecognised when the charity’s contractual obligations expire or are discharged or cancelled

2 . CRITICAL ACCOUNTING ESTIMATES AND JUDGMENT

In the application of the Charity’s accounting policies, the trustees are required to make judgements, estimates and assumptions about the carrying amount of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an on-going basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised where the revision affects only that period, or in the period of the revision and future periods where the revision affects both current and future periods.

No critical accounting estimates and judgements have been made in preparing these financial statements.

These unaudited financial statements have been subjected to independent examination. See report on page 8.
