Krylov Complexity for Open Quantum System: Dissipation and Decoherence
Arpan Bhattacharyya, Sayed Gool, S. Shajidul Haque
We investigate Krylov complexity in open quantum systems using Lindblad master equations for bosonic bath models, with particular emphasis on the Caldeira--Leggett model. Krylov co…

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…
