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…
Electron correlations in the kagome flat band metal
Fang Xie, Yuan Fang, Ying Li +7
Kagome metals offer a unique platform for investigating robust electron-correlation effects because of their lattice geometry, flat bands and multi-orbital nature. In the cases wit…
Influence of graphene on the electronic and magnetic properties of an iron(III) porphyrin chloride complex
Young-Joon Song, Charlotte Gallenkamp, Genís Lleopart +2
Although iron-based single atom catalysts are regarded as a promising alternative to precious metal catalysts, their precise electronic structures during catalysis still pose chall…
Magnetic properties of multi-domain epitaxial EuPd thin films
Alfons G. Schuck, Sebastian Kölsch, Adrian Valadkhani +3
Europium intermetallic compounds show a variety of different ground states and anomalous physical properties due to the interactions between the localized 4f electrons and the delo…
Topology of SmB6 revisited by means of topological quantum chemistry
Mikel Iraola, Iñigo Robredo, TItus Neupert +3
The mixed-valence compound SmB6 with partially filled samarium 4f flat bands hybridizing with 5d conduction bands is a paramount example of a correlated topological heavy-fermion s…
Strain control of band topology and surface states in antiferromagnetic EuCdAs
Nayra A. Álvarez Pari, V. K. Bharadwaj, R. Jaeschke-Ubiergo +4
Topological semimetal antiferromagnets provide a rich source of exotic topological states which can be controlled by manipulating the orientation of the Néel vector, or by modulati…
