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 EuCd $_{2}$ As $_{2}$

Adrian Valadkhani, Mikel Iraola, Axel Fünfhaus +4

Motivated by the wealth of proposals and realizations of nontrivial topological phases in EuCd $_{2}$ As $_{2}$ , such as a Weyl semimetallic state and the recently discussed semimetallic…
