Exact projected entangled pair ground states with topological Euler invariant
Thorsten B. Wahl, Wojciech J. Jankowski, Adrien Bouhon +2
We report on a class of gapped projected entangled pair states (PEPS) with non-trivial Euler topology motivated by recent progress in band geometry. In the non-interacting limit, t…

Anomalous multi-gap topological phases in periodically driven quantum rotors
Volker Karle, Mikhail Lemeshko, Adrien Bouhon +2
We demonstrate that periodically driven quantum rotors provide a promising and broadly applicable platform to implement multi-gap topological phases, where groups of bands can acqu…
