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…
Bound states and local topological phase diagram of classical impurity spins coupled to a Chern insulator
Simon Michel, Axel Fünfhaus, Robin Quade +2
The existence of bound states induced by local impurities coupled to an insulating host depends decisively on the global topological properties of the host's electronic structure.…
Influence of magnetism, strain and pressure on the band topology of EuCdAs
Adrian Valadkhani, Mikel Iraola, Axel Fünfhaus +4
Motivated by the wealth of proposals and realizations of nontrivial topological phases in EuCdAs, such as a Weyl semimetallic state and the recently discussed semimetallic…
Winding vectors of topological defects: Multiband Chern numbers
Axel Fünfhaus, Thilo Kopp, Elias Lettl
Chern numbers can be calculated within a frame of vortex fields related to phase conventions of a wave function. In a band protected by gaps the Chern number is equivalent to the t…
