SCIENTIFIC REPORT ON THE PSI-K WORKSHOP: “ATOMIC SCALE MATERIALS MICROSCOPY: THEORY MEETS EXPERIMENT”

Psi-k workshop on
“Atomic scale materials microscopy: theory meets experiment”
National Railway Museum, York (UK)
26-28 June 2017

Summary:

Atomic scale materials characterization is now one of the major drivers of technological innovation in areas such as nanoelectronics, catalysis, medicine, clean energy generation and energy storage. This can in a large part be attributed to advances in electron and scanning probe microscopies, which are now able to provide atomically resolved structural, chemical and electronic characterization of a wide range of functional materials. However, the types of systems relevant to applications, which include surfaces, interfaces, nanocrystals and two-dimensional materials, are complex and interpreting experimental images and spectra is often extremely challenging. On the other hand, parallel advances in theoretical approaches means that theory can often offer invaluable guidance. These approaches include first principles methods for structure prediction, simulation of scanning probe and electron microscopy images, and prediction of various spectroscopic signatures (e.g. EELS and STS). Some of the most impressive examples of this kind of research in recent years have combined complementary theoretical and experimental approaches in a synergistic way to unravel the complex structure of materials. This type of integrated approach is increasingly being recognised as critical to advanced materials research and development by both industry and research funders.

It was in this context that the Psi-k workshop: “Atomic scale materials microscopy: theory meets experiment” was held between the 26th and 28th of June 2017 at the National Railway Museum in York (UK). The scientific focus was on the application and development of first principles methods that, in synergy with advanced microscopy techniques (e.g. TEM, EELS, STM, AFM), can help to unravel the structure and properties of materials at the atomic scale. Open to both experts and newcomers the aim was to provide a rounded overview of emerging methods and challenges in the field, and provide an opportunity for in-depth discussion and exchange of ideas.

Scientific Report regarding the CECAM Workshop: “Tackling complexity of the nano/bio interface – computational and experimental approaches”

Organizers:   Thomas Frauenheim (University of Bremen)

Qiang Cui (University of Wisconsin, Madison, USA)

Bob Hamers, University of Wisconsin, Madison, USA)

Joel Pedersen, University of Wisconsin, Madison, USA)

Location:       University of Bremen, Germany,

12th June until 16th June 2017

  1. Summary

The workshop “Tackling Complexity of the Nano/Bio Interface – Computational and Experimental Approaches” was held at the University of Bremen, Germany from June 12th to 16th 2017. In total, 72 participants from Belgium, Brazil, Finland, Ireland, Luxemburg, The Netherlands, Portugal, Slovenia, Spain, Sweden, Switzerland, Russia, France, Germany, UK and US attended the workshop.

The programme consisted of 28 invited lectures, one poster session presenting 27 posters and many events (reception / conference dinner) to allow for informal exchange. The lectures were scheduled to last 40 min, including 5-10 min discussion time. In addition to this extended time for discussion, the chairpersons were instructed to introduce the subject of the session and to actively participate in the discussion. This “Gordon-conference-style” was essential to guarantee a vivid discussion. The organizers ensured that well-established scientists acted as invited speakers and chairpersons.

Scientific report on “HoW exciting! Workshop on excitations in solids Humboldt-Universität zu Berlin”, Berlin, Germany August 3 – 11, 2016

 

The third Berlin edition of the “HoW exciting! Workshop on excitations in solids” was a very successful event. It took place in the Campus Adlershof of the Humboldt-Universität zu Berlin. The subject of the workshop, namely excitations in solids, is extremely up-to-date, attracting the attention of a vast interdisciplinary community. Technological applications based on excitations in solids are closely interconnected with the fundamental physical mechanisms ruling them. A deep understanding of such basic properties is therefore essential and makes the role of theory crucial in this respect. Assessing the state of the art of the theoretical approaches to address excited-state properties of materials and establishing their link with the most recent experimental observations were the main goals of this workshop, which can be considered successfully achieved.

14th ETSF Young Researchers’ Meeting (Tarragona)

In 2017, the ETSF Young Researchers’ Meeting made its way to Tarragona, Spain for the first time. Sunny weather, great food, a beautiful old city and the kind hosts at the Catalan Institute for Chemical Research (ICIQ) provided a fantastic setting for a week of science that will stay in our memory.

The Young Researchers’ Meeting (YRM) of the European Theoretical Spectroscopy Facility (ETSF) is a workshop organised by young researchers for young researchers. Every year, postdocs, PhD students and Master students gather from all over Europe to discuss problems and recent advances in theoretical and computational methods for the study of the electronic and optical properties of materials. The YRM is where you can present your work in progress, float new ideas, and learn from others at your own level – both scientifically and personally. Talks at the YRM are 25 minutes, which gives you enough time to introduce your topic, what you did and, crucially, how you did it. Each session starts with an introductory keynote that provides an overview of the field, introduces the theoretical framework and points out open questions.

SCIENTIFIC REPORT ON THE “18TH INTERNATIONAL WORKSHOP ON COMPUTATIONAL PHYSICS AND MATERIALS SCIENCE: TOTAL ENERGY AND FORCE METHODS”

18th Total Energy Workshop, ICTP, Trieste (Italy), 12-14 January 2017

Group picture from the 18th Total Energy International Workshop, ICTP, Trieste, January 2017

The “Total Energy” Workshop is held traditionally in Trieste every two years, since 1987. It is devoted to recent advances in computational condensed matter physics and materials science, based on realistic calculations of the electronic structure of complex systems. It has become one of the most popular regular events of the international ab-initio electronic-structure community. The 2017 edition confirmed this tradition, with a large number of participants, lively discussions and, furthermore, with an impressive number of contributed posters. Overview, speakers list, program with the relevant material (Conference Book, abstracts, list of attendees, …) are available on the web page: http://indico.ictp.it/event/7948/overview

Report

The Workshop involved 225 attendees, including Directors, Scientific Committee members, speakers, and selected participants.

Following the tradition of the previous meetings of the series, the Workshop has been structured in thematic sessions with oral presentations by invitation only. The aim was to gather speakers presenting current topics of research of broad interest as well as future research directions for the electronic structure community. The chairpersons introduced each session with a short overview (about 5 min) to set the subject and point out open problems.  The introductions were very useful, especially for those people working on other subjects. In addition, large space was devoted to discussion. This format has been greatly appreciated and contributed to create, most noteworthy, a lively atmosphere.

Selected contributions from participants have been solicited as posters. The large number of selected posters (140) has been a testament of the enthusiastic and active participation of the attendees. Consequently, two large poster sessions have been organized.

In Honor of Walter Kohn

The Workshop included one special Lecture and one entire session in honor of Walter Kohn, Continue reading SCIENTIFIC REPORT ON THE “18TH INTERNATIONAL WORKSHOP ON COMPUTATIONAL PHYSICS AND MATERIALS SCIENCE: TOTAL ENERGY AND FORCE METHODS”

Questaal Hands-On Course

Daresbury Laboratory was pleased to welcome 40 scientists to the “Questaal Hands-On Course” which took place over four days between May 16th and 19th.  The Questaal software suite features the first all-electron GW code and the first implementation of the quasiparticle-self-consistent GW method, which is significantly more accurate and reliable than conventional density-functional methods.  The focus of the course was to introduce these advanced methods to researchers already familiar with electronic structure calculations and to teach them the practical details needed to perform such calculations for materials and systems relevant to their individual research areas.
