Autumn-School on Correlated Electrons 2021:
Simulating Correlations with Computers

08 November 2021

by Eva Pavarini and Erik Koch

The eleventh edition of the Autumn School on Correlated Electrons, led by Eva Pavarini from the Institute for Advanced Simulation (IAS) and Erik Koch of the Jülich Supercomputer Centre (JSC), focused on quantum simulations of correlated materials. In response to the corona pandemics, the school was held for the second time in an on-line format.

More than 200 students from all over the globe followed the lectures via zoom. Thanks to their and the lecturer's enthusiasm presentations and discussions were very lively despite the geographical distance. To accommodate as many of the registered participants as possible, lecture times were shifted to the afternoon and early evening. This nevertheless did not deter students, for whom the lectures fell in the small hours of the early morning, from attending.

The lectures addressed the challenges of modeling and simulating strong correlations in materials. After an introduction to the fundamentals of many-body physics and quantum chemistry, different approaches to the many-body problem where compared, using the simplest non-trivial model, the Hubbard dimer. Further lectures introduced modern methods for simulating correlated materials and discussed the promises that quantum simulations may hold.

Students enthusiastically took the opportunity to discuss with world leaders in the field of correlated quantum materials. In addition, breakout-room sessions allowed them to present their projects and expand their network in the global research community, represented by participants from, besides Germany and the EU, the UK, Russia, Israel, Jordan, Iran, India, Nepal, Bangladesh, Pakistan, Thailand, Indonesia, China, Taiwan, South Korea, Japan, Australia, Morocco, Algeria, Benin, Ghana, Nigeria, Rwanda, Cameroon, Brazil, Ecuador, Mexico, the USA, and Canada.

To enhance the impact of the courses, comprehensive lecture notes were published as a book that was ready at the beginning of the school. These lecture notes will help to fill the acute gap between introductory textbooks and the research literature, as is evident from the high demand also outside the school. To be as widely accessible as possible, the lecture notes have been made available via Open Access:
