Anomalous Mixed-State Floquet Topology in One-Dimensional Open Quantum Systems
Görkem D. Dinc, Alexander Schnell, Andy M. Martin
We investigate the non-equilibrium topology of a periodically driven, dissipative Su-Schrieffer-Heeger chain using the ensemble geometric phase (EGP) -a generali…

Edge state behavior of interacting Bosons in a Su-Schrieffer-Heeger lattice
Anirban Ghosh, Andy Martin
In the low momentum regime, the Su-Schrieffer-Heeger (SSH) model's key characteristics are encapsulated by a Dirac-type Hamiltonian in continuum space, i.e., the localized states e…

Switching of post quench reflection asymmetry in an embedded non-Hermitian Su-Schrieffer-Heeger system
Anirban Ghosh, Andy Martin
A quench in a Su-Schrieffer-Heeger lattice across the topological boundary initialized with an edge state leads to transport across the chain. We consider such a quench in an effec…
