Liouvillian topology and nonreciprocal dynamics in open Floquet chains
Florian Koch, Yu-Min Hu, Jan Carl Budich
Open quantum systems far from thermal equilibrium can exhibit remarkable physical phenomena including topological properties without a direct equilibrium counterpart. Along these l…

Dissipative frequency converter: from Lindblad dynamics to non-Hermitian topology
Florian Koch, Jan Carl Budich
A topological frequency converter represents a dynamical counterpart of the integer quantum Hall effect, where a two-level system enacts a quantized time-averaged power transfer be…
