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…
