Mixed-State Topology in One-Dimensional Open Floquet Systems
Görkem D. Dinc, Alexander Schnell, Andy M. Martin
We investigate the non-equilibrium topology of the steady state of a periodically driven, dissipative Su-Schrieffer-Heeger (SSH) chain using the ensemble geometric phase (EGP) $ϕ_{…
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…
Asymmetrical post quench transport in an embedded parity time symmetric Su-Schrieffer-Heeger system
Anirban Ghosh, Andy Martin
We study the effect of PT-symmetric non-hermiticity on the transport of edge state probability density arising as a result of a quench. A hybrid system involving a PT-symmetric SSH…
