New Psi-k Chair

As we move into a new year Psi-k is delighted to announce the election of a new Chair, Professor Arash Mostofi of Imperial College London. Professor Mostofi will follow on from previous Chair, Professor Peter Haynes, who has now come to the end of his term.

Arash Mostofi is Professor of Theory and Simulation of Materials in the Departments of Materials and Physics at Imperial College London. His research is dedicated to the development and application of first-principles modelling tools for the theory and simulation of materials. He is an original author and developer of the Wannier90 and ONETEP codes and his research interests include electronic structure software development, 2D materials, defects and interfaces, and perovskite and layered perovskite oxides.

We would like to take this opportunity to thank Professor Haynes for his leadership of Psi-k over the last three years and look forward to working with him as the Chair of the next Psi-k Conference that will be held in Lausanne, Switzerland in 2025.

Psi-k supported focus session at DPG Meeting

Frontiers of Electronic-Structure Theory @ DPG Meeting 2023

The DPG Spring Meeting of the Condensed Matter Division is the largest European physics conference (the second largest physics conference worldwide), covering all aspects of condensed matter and chemical physics, and materials science. For many years, Psi-k has supported a Focus Session on Frontiers of Electronic-Structure Theory with a special focus topic that changes from year to year.  In 2023 the focus will be on Large-scale Calculations Enabled by Sharing Developments and Tools, organised by Claudia Draxl, Andris Gulans, Xavier Gonze, and Dorothea Golze.

Abstract

Electronic-structure calculations, based on density-functional theory (DFT) and methodology beyond, are getting increasingly involved as they face the following challenges: First, investigations of modern materials typically require large unit cells, owing to complex crystal structures, mixed compositions, internal interfaces, etc. Second, at the same time, they often require advanced methods, including hybrid functionals of DFT, Green-function techniques from many-body perturbation theory (MBPT), high-level wavefunction-based methods like coupled-cluster (CC) theory, or quantum Monte-Carlo simulations. All these methods should ideally be implemented in scientific software that is running efficiently on modern supercomputers. With both methodology and computer architectures exhibiting increasing complexity, collaborative development and shared tools, including ready-to-use libraries and codes, are becoming indispensable. This interdisciplinary symposium will cover recent progress in the broad area of electron-structure methods and highly-sophisticated tools that enable the entire community to explore most exciting materials from different perspectives to either predict peculiar features or get insight into measured counterparts. The invited talks will be given by leading and emerging experts in the field. Contributed talks and posters will be from researchers working on developing methods and tools as well as applications to advanced materials.

Unfortunately, due to the venues decision not to host external events, there will not be a Psi-k Get Together this year. However, we look forward to seeing you all at the focus session and we will endeavour to include the Psi-k Get Together at next year’s meeting.

TREX School on QMC with TurboRVB

We are inviting young students and more senior researchers interested in learning ab initio quantum Monte Carlo, one of the most accurate and versatile approaches for materials and electronic structure calculations, to apply for the upcoming TREX School on QMC with TurboRVB, taking place from 3-7 July 2023 in Trieste, Italy. This QMC summer school is organized by TREX project and it will be held in the Scuola Internazionale Superiore di Studi Avanzati (SISSA).

It will be a great event to learn TurboRVB (QMC algorithms), TurboGenius (command-line tools to make QMC calculations user friendly), and TurboWorkflows (high-throughput computations) codes for QMC applications and tutorials. And, this time, to meet your peers and colleagues in person.
After many years of development, the TurboRVB code will be officially released as an open source package during this school.

Why should you join the School?

  • The TREX project is offering participants free lodging, coffee breaks, lunch breaks and a social dinner during the School. This will be the perfect occasion to meet your peers and colleagues in person, share experiences and learn more about QMC methods and how to use them in practice.
  • Participants are invited to submit their poster contributions and present results and ongoing activities at the School.  The best poster winner will win a stay of one week at Sorbonne University, Paris, in the Quantum Theory of Materials group (IMPMC)
  • After many years of development, the TurboRVB code will be officially released as an open source package during this school. Do not miss this event!
  • Get the chance to explore beautiful Trieste, top-ranked in Italy for its quality of life, and to discover this town renowned for its scientific institutions. If you want to extend your stay in Trieste for one more week, the week after the school there will be a workshop organized at the ICTP about “QMC methods at work for describing novel states of matter”, a perfect follow-up of our school! Please, note that a separate registration is required for the ICTP workshop. Please, also note that the TREX project is not covering participant’s travel nor extra costs.

Important information

  • We have a limited number of seats so please consider submitting your application as soon as possible. Deadline for application is  28.05.2023 COB.
  • Attendees are supposed to have a background in condensed matter theory and/or quantum chemistry.

Psi-k Working Groups

Dear all

Our working groups are the heart of the Psi-k community, and the Board of Trustees wishes to express its thanks to the leaders and members of the current groups for serving us in these roles.

Following on from the presentation and discussion at the Annual Community Meeting in December, the Board of Trustees has now approved the titles and scopes of the new working groups. These can be found on the Psi-k web site.

We now need to select members and a leader for each working group in time for them to participate in the review of outline workshop proposals in July. Their roles and responsibilities are also detailed on the web page above. Other key tasks for these new groups will be to assist in the planning of the scientific programme for the next Psi-k Conference in 2025 and the shortlisting of nominations for Psi-k awards.

Psi-k is committed to promoting equality, diversity and inclusion at all levels, paying particular attention to:

  • gender balance;
  • spread across career stages;
  • geographical representation.

In particular, it has been agreed that each working group will include one member who is an early career researcher* and one member from outside Europe.

The current working groups were established in 2018 with the expectation that they would be refreshed at the following Conference. The expectation now is that leaders who have served for five years will normally stand down from this role, but that they may be nominated to stay on as members to provide continuity. Current members who have been particularly active may also be nominated to continue. It is anticipated that around half of the membership of the new working groups will be taking on this role for the first time.

Individuals may self-nominate, but the Board of Trustees is particularly keen to seek nominations of individuals who may be reluctant to put themselves forward, especially those working in eastern Europe or from under-represented groups within our community. We urge senior members of the Psi-k community to consider carefully whom they might nominate.

Nominations should be submitted via this Google form. There is no formal deadline, with nominations being considered as they are received, but the trustees will begin inviting new members from the middle of April. You are welcome to submit more than one nomination.

Best wishes,

Peter Haynes
Psi-k Chair of Trustees

*An early career researcher is someone holding a PhD but who does not yet hold a permanent position within a university, research institute or company.
