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…

Controlling Liouvillian topological phases via Hamiltonian band topology under chiral symmetry
Shu Long, Hong-Sen Yin, Chao Yang +3
We establish a direct connection between Hamiltonian band topology and the Liouvillian spectral winding of open quantum systems with quadratic dissipations. This allows the band to…
