Autumn-School on Correlated Electrons 2020:
Topology, Entanglement, and Strong Correlations

07 October 2020

by Eva Pavarini and Erik Koch

This year's Autumn School on Correlated Electrons, led by Eva Pavarini from the Institute for Advanced Simulation (IAS) and Erik Koch from the Jülich Supercomputer Centre (JSC), marked the tenth anniversary of the series.  In response to the corona pandemics the format had to be changed to an online edition:  Well over 100 participants from all over the world followed the lectures via zoom. Thanks to the enthusiasm of students and lecturers both presentations and discussions worked extremely well 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 physics of strong correlations, with a focus on topology and entanglement. After an introduction to mean-field methods, lectures covered modern techniques for confronting the many-body problem, topological aspects of semimetals, metals and superconductors as well as the physics of Mott systems. Furthermore, the nature of entanglement and its quantification were introduced. The school was completed by lectures covering state-of-the-art methods for simulating strongly correlated matter. 

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, Russia, Turkey, Iran, India, Thailand, China, Taiwan, South Korea, Japan, Australia, Argentina, Brazil, Colombia, 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:
