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…
