Many-body Euler topology
Axel Fünfhaus, Titus Neupert, Thilo Kopp +1
Integer and fractional Chern insulators exhibit a nonzero quantized anomalous Hall conductivity due to a spontaneous breaking of time reversal symmetry. To identify nontrivial topo…
Band representations in Strongly Correlated Settings: The Kitaev Honeycomb Model
Axel Fünfhaus, Mikel García-Díez, M. G. Vergniory +3
In the study of quantum spin liquids, the Kitaev model plays a pivotal role due to the fact that its ground state is exactly known as well as the fact that it may be realized in st…
Artificial Atoms Based on Correlated Materials
Jochen Mannhart, Hans Boschker, Thilo Kopp +1
Low-dimensional electron systems fabricated from quantum matter have in recent years become available and are being explored with great intensity. This article gives an overview of…
