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…
Topological Phase Transitions of Interacting Fermions in the Presence of a Commensurate Magnetic Flux
Axel Fünfhaus, Marius Möller, Thilo Kopp +1
Motivated by recently reported magnetic-field induced topological phases in ultracold atoms and correlated Moiré materials, we investigate topological phase transitions in a minima…
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…
Emerging magnetism and electronic phase separation at titanate interfaces
N. Pavlenko, T. Kopp, J. Mannhart
The emergence of magnetism in otherwise nonmagnetic compounds and its underlying mechanisms have become the subject of intense research. Here we demonstrate that the nonmagnetic ox…
Magnetically ordered state at correlated oxide interfaces: the role of random oxygen defects
Natalia Pavlenko, Thilo Kopp
Using an effective one-band Hubbard model with disorder, we consider magnetic states of the correlated oxide interfaces, where effective hole self-doping and a magnetially ordered…
Magnetism and superconductivity at LAO/STO-interfaces: the role of Ti 3d interface electrons
N. Pavlenko, T. Kopp, E. Y. Tsymbal +2
Ferromagnetism and superconductivity are in most cases adverse. However, recent experiments reveal that they coexist at interfaces of LaAlO3 and SrTiO3. We analyze the magnetic sta…
