Dynamics of monitored SSH Model in Krylov Space: From Complexity to Quantum Fisher Information

Nilachal Chakrabarti, Neha Nirbhan, Arpan Bhattacharyya

In this paper, we investigate the dynamics of a non-Hermitian SSH model that arises out of the no-click limit of a monitored SSH model in the Krylov space. We find that the saturat…
