Korrelationstage 2023

Korrelationstage 2023
International Workshop
Scientific coordinators: Ilya Eremin, Lars Fritz, Maia Vergniory

The workshop took place at the MPIPKS in Dresden on September 11 – September 15, 2023 and continued a long standing tradition in bringing together researchers mostly working in the field of strongly correlated (electronic) systems and related areas. The main focus of this event was to capture the new developments in this active field, with a particular emphasis on the new realizations of the correlated quantum matter including but not limited to heterostructures of 2d materials as well as analytical and numerical methods development, which happened over the past several years. The format of the meeting was chosen such that there were only very few invited talks and most of the research talks, selected from the submitted contributions, were presented by junior (non-tenured) scientists. The poster presentations were solicited from everybody.

The workshop covered a range of topics, including the novel development in the field of non-trivial topology in correlated and magnetic systems; interplay of topology and superconductivity, recent advances in the numerical methods like DMRG and quantum Monte Carlo, development of the new algorithms for the quantum computer. During the workshop a number of phenomenological and microscopic theories have been discussed in informal but serious manner. In addition this workshop promoted scientific exchange and interaction between researchers working in these and related areas.

Over 90 participants from Europe, Asia and USA, took part in the meeting. The program included 40 oral presentations, both invited and contributed, as well as two poster sessions with overall 54 posters. The interchange of points of view between participants with distinct scientific interests gave rise to a highly stimulating atmosphere. During the workshop, a number of new and exciting results have been presented by, e.g., Frank Schindler (Imperial College London) on “Nonlinear breathers in obstructed atomic bands”, Johannes Knolle (Technische Universität München) on “Anomalous quantum oscillations in metals and insulators”, Jonah Waissman (The Hebrew University of Jerusalem) on “Detecting emergent magnons in graphene via thermal transport”, Natalia Chepiga (TU Delft) on “Resilient infinite randomness criticality for a disordered chain of interacting Majorana fermions”, and Mathias Scheurer (University of Stuttgart)  on “Exotic many-body physics in van der Waals moiré systems”. Many other, especially young, participants presented talks of high quality and showed new and interesting results. The talks, discussions, and posters at Korrelationstage 2023 demonstrated that the field of correlated electrons is developing rapidly and has great prospects.

Two main results of the Workshop are (i) a focused exchange of ideas on the recent theoretical developments in the field of strongly correlated electrons and related systems, and (ii) an involvement of young scientists in the discussion which has stimulated new research collaborations.

We would like to thank MPIPKS for its hospitality and excellent infrastructure provided to the participants of the workshop. We also would like to thank the team of secretaries and, in particular, Katrin Lantsch for their kind assistance and excellent support of this meeting.
