The Psi-k Community

MISSION: 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 organization of conferences, workshops, tutorials and training schools as well as the dissemination of scientific thinking in society.

Psi-k is a bottom-up researchers’ network, established in 1994, to build strength and cooperation in the field of computational electronic structure. Psi-k activities are coordinated by a Board of Trustees, a Scientific Advisory Committee, and 16 Working Groups. These activities encompass the organization or co-sponsoring of ~30 workshops, conferences, schools or tutorials every year, an annual research conference jointly with CECAM, and a major conference covering the entire field every 5 years.

In addition, Psi-k produces a regular newsletter with extensive scientific highlights, and allows researchers to advertise job openings, events, and other topics of mutual interest through its 5000+ members mailing list.

This new website — introduced in  2015 to replace a venerable old site that provided sterling service over many years — offers a much more flexible modern design and functionality and it is to be hoped that it will provide even more stimulus for collaboration and cooperation amongst its members. Instructions regarding how to use it are here.

Psi-k is a registered charity and can only continue to operate thanks to the contributions from our member organisations and institutions. If you would like to make a donation to Psi-k please contact us.

Psi-k 2020 conference postponed to next year (August 2021)

Dear Psi-k’ers,

As mentioned earlier, the COVID-19 created much uncertainty regarding whether the Psi-k conference could be held this year. It has now been decided by the Board of Trustees that it is indeed not possible to ensure that the conference can take place this September. The conference is therefore postponed to next year, and it will be held on August 23-26, 2021, preserving the same format, plenary and invited speakers, and symposia.

The registration platform will be reopened later this year – we will contact you directly in the coming days in case you had already registered for this year.

We are in the process of reconfirming the participation of the speakers.

Thank you for your understanding and we look forward to meeting you next year!

Best regards,

Nicola Marzari

Big Data Summer: A summer school of the BiGmax Network

Platja d’Aro, Spain, September 9 – 13, 2019

Webpage:  https://th.fhi-berlin.mpg.de/meetings//BiGmax-Summer-2019/

Organizers:

Gerhard Dehm
Max-Planck-Institut für Eisenforschung, Düsseldorf, Germany
Claudia Draxl
Humboldt-Universität zu Berlin, Berlin, Germany
Matthias Scheffler
Fritz Haber Institute of the Max Planck Society, Berlin, Germany
Jilles Vreeken
CISPA – Helmholtz Center for Information Security, Germany

Scope:

Materials science is entering an era where the growth of data from experiments and simulations is expanding beyond a level that is addressable by established scientific methods. The so-called “4 V challenge” – concerning Volume (the amount of data), Variety (the heterogeneity of form and meaning of data), Velocity (the rate at which data may change or new data arrive), and Veracity (uncertainty of quality) is clearly becoming eminent. Issues are, for example, an early discrimination between valuable and irrelevant experimental data, understanding errors in both experiment and theory, and assigning error bars and trust levels to density-functional theory high-throughput screening results, just to name a few. Most importantly, however, is that Big Data of materials science provide a significant chance for new insight and knowledge gain when fully exploiting its information by artificial intelligence concepts and methods. All the above aspects – from data processing to exploiting the potentials of data-driven materials science – require new and dedicated approaches.

Psi-k Administration Update

Dear Psi-k Community

This is just a quick update from Psi-k administration.

Firstly, I hope that you are all doing OK and that you are managing to adapt to this new and strange situation we all find ourselves in? The last few weeks have certainly been challenging for everyone.

I am now fully set-up for home working and will be answering all of the emails received over the last few weeks in the next day or two. Thank you for your patience. As you can imagine there were certain parts of my day-to-day job that needed to be prioritised in order to ensure that things could go on as normally as possible. Everything is now in order and I can start to catch up on emails and actions that had to be put to one side.

I hope that you all continue to stay safe and that we can return to normal quickly.

Best Regards

Damian

REPORT: MSSC2019 – AB INITIO MODELLING IN SOLID STATE CHEMISTRY

The Department of Chemistry and the Thomas Young Centre at Imperial College London and the Theoretical Chemistry Group of the University of Torino, in collaboration with the Computational
Materials Science Group of the Science and Technology Facilities Council (STFC), organized the 2019 MSSC Summer School on the “ab initio modelling of crystalline and defective solids with the CRYSTAL code”.

CRYSTAL is a general-purpose program for the study of periodic solids. It uses a local basis set comprised of Gaussian type functions and can be used to perform calculations at the Hartree-Fock, density functional or global and range-separated hybrid functionals (e.g. B3LYP, HSE06), double hybrid levels of theory. Analytical first derivatives with respect to the nuclear coordinates and cell parameters and analytical derivatives, up to fourth order, with respect to an applied electric field (CPHF/CPKS) are available.

The school provided an overview of the underlying theory and fundamental issues affecting use of the code, with particular emphasis on practical issues in obtaining reliable data efficiently using modern computer hardware.

All information about the school can be found on this website:

Registration for Psi-k 2020 is now open!!!

SwissTech Convention Centre, Lausanne, Switzerland
Monday 14 – Thursday 17 September 2020

 

IMPORTANT NOTICE

With the current COVID-19 situation causing the cancellation of major events and conferences around the world, there is now significant uncertainty regarding Psi-k 2020 as well. Although we are still hoping that the conference can take place as planned, we are following the evolution of the situation closely and expect to have a clearer idea in the next few weeks regarding whether to maintain the event, or whether to postpone it to next year.

In order to avoid incurring any potential cancellation costs, we recommend that you refrain from making any travel plans for the time being.

The registration system has been suspended until a final decision is made — if the conference is maintained this year, all registration deadlines will be extended. Participants who had already registered will be contacted once a final decision is made.

Thank you for your patience in these exceptional time, and stay safe!


This is the largest event worldwide in first-principles simulations; it is held every 5 years (the last two editions, in Berlin in 2010 and in San Sebastian in 2015, had more than 1000 participants each), and with 7 plenary talks, 140 invited talks, and 170 contributed talks it promises to be the most exciting, defining event in the field.

Early-bird deadline is May 1, 2020 – one can register right away, and submit an abstract later (by May 1, 2020, to be considered for a contributed talk, or by Aug. 1, 2020, for a poster). All information – including registration, program, accommodation, and childcare – is available at https://www.psik2020.net. Continue reading Registration for Psi-k 2020 is now open!!!

Scientific Report on the “Workshop on Computational Physics and Material Science: Total Energy and Force Methods 2020”

This event was the latest in the “mini” series associated with the “Total Energy and Force Methods” workshops, held at ICTP in Trieste every two years. Since 1987 the Trieste workshops have taken place in odd-numbered years, alternating with the mini workshops, held each even-numbered year in a different location. The most recent workshops of the mini series took place in Madrid (2000), Tenerife (2002), Paris (2004), Cambridge (2006), Bonn (2008), Shanghai (2010), Barcelona (2012), Lausanne (2014), Luxembourg (2016), and Cambridge (2018).

The workshop focused on the most recent developments in the field of electronic structure methods from the first-principles perspective, their diverse applications and mathematical foundations. The numerous approaches that are developed and used in the electronic-structure community provide the foundation for computing many physical and chemical properties of solids, liquids, and low-dimensional systems. However, there are numerous challenging applications for which the level of approximation is insufficient or where computational costs are prohibitive for accurate quantitative prediction of material properties. Therefore, continued efforts are devoted to the improvement of existing methods, and the development of new methods.

AB INITIO MODELLING OF ADVANCED MATERIALS (AMM 2019)

Workshop Ab initio Modelling of Advanced Materials (AMM 2019)
10-13 September 2019, Onegin hotel, Ekaterinburg, Russia

From 10th to 13rd September 2019 the second workshop AMM2019 devoted to the recent progress in the development and application of ab-initio based methods of calculation and thermodynamic/kinetic modeling for microstructure and finite-temperature properties of a wide range of materials was held at conference hall of Onegin hotel in Ekaterinburg, Russia. This workshop welcomed 73 participants from 14 countries (including organizers), and 3 staff members. During the workshop, 25 oral talks and 14 key-note lectures were presented. The event was sponsored Psi-k organization, and the Institute of Metal Physics Ural division RAS (Ekaterinburg, Russia).

The purpose of this workshop was to brings together prominent scientists from the area of theoretical modelling to assess the state of the art in applications of the electronic structure theory for the knowledge-based design of advanced materials. Because the AMM2019 workshop was scheduled as a satellite to the international conference on magnetism EASTMAG-2019, the cooperation-promoting atmosphere of the both events were provided. The special topic of AMM2019 was related to problems of magnetism and magnetic materials. The main focus of the AMM2019 was to provide a fruitful framework for development and dissemination of novel ideas and concepts in order to resolve the present challenges in the field and development of new strategy for design of the materials by using combined multi-disciplinary efforts.
