Krylov Complexity: Flat bands and Carroll breaking deformations
Aritra Banerjee, Arpan Bhattacharyya, Rudranil Basu +1
Systems with flat band structures, when written in the language of Compact Localised States (CLS), have been shown to be explicitly invariant under supertranslation symmetries, mak…
Stochastic Krylov Dynamics: Revisiting Operator Growth in Open Quantum Systems
Arpan Bhattacharyya, S. Shajidul Haque, Jeff Murugan +2
In closed quantum systems, Krylov complexity admits a geometric description; operator growth is equivalent to Hamiltonian flow in an emergent phase space whose structure is fixed b…
Dynamics of entanglement entropy for a locally monitored lattice gauge theory
Nisa Ara, Arpan Bhattacharyya, Nilachal Chakrabarti +2
The dimensional gauge theory is the simplest model that allows for quantum computation or quantum simulation to probe the fundamental aspects of a gauge theory coupled…
Effects of monitoring on entanglement dynamics for D lattice gauge theory
Nilachal Chakrabarti, Nisa Ara, Neha Nirbhan +2
The -dimensional gauge theory is the simplest model that allows for quantum simulation to probe the fundamental aspects of a gauge theory coupled with dynamica…
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…
Symmetry Resolution in non-Lorentzian Field Theories
Aritra Banerjee, Rudranil Basu, Arpan Bhattacharyya +1
Starting from the computation of Symmetry Resolved Entanglement Entropy (SREE) for boosted intervals in a two dimensional Conformal Field Theory, we compute the same in various non…
