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…

Boundary Floquet Control of Bulk non-Hermitian Systems
Yu-Min Hu, Yu-Bo Shi, Linhu Li +5
Boundary perturbations are generally irrelevant for bulk properties in the thermodynamic limit, as they are edge-confined and subextensive. We show that this expectation breaks dow…

Asymptotic Exceptional Steady States in Dissipative Dynamics
Yu-Min Hu, Jan Carl Budich
Spectral degeneracies in Liouvillian generators of dissipative dynamics generically occur as exceptional points, where the corresponding non-Hermitian operator becomes non-diagonal…
