Bilayer Haldane system: Topological characterization and adiabatic passages connecting Chern phases
Sourav Bhattacharjee, Souvik Bandyopadhyay, Diptiman Sen +1
We present a complete topological characterization of a bilayer composite of two Chern insulators (specifically, Haldane models) and explicitly establish the bulk-boundary correspo…
Observing Dynamical Quantum Phase Transitions through Quasilocal String Operators
Souvik Bandyopadhyay, Anatoli Polkovnikov, Amit Dutta
We analyze signatures of the dynamical quantum phase transitions in physical observables. In particular, we show that both the expectation value and various out of time order corre…
Dissipative preparation of many-body Floquet Chern insulators
Souvik Bandyopadhyay, Amit Dutta
Considering coupling to a micro-structured bath as a relaxation mechanism in a periodically driven dissipative Haldane model, we establish that the system may be tuned to a strobos…
Unitary preparation of many body Chern insulators: Adiabatic bulk boundary correspondence
Souvik Bandyopadhyay, Amit Dutta
We approach the long-standing problem of preparing an out-of-equilibrium many-body Chern insulator (CI) and associated bulk-boundary correspondence unitarily. Herein, this is addre…
Growth of mutual information in a quenched one-dimensional open quantum many body system
Somnath Maity, Souvik Bandyopadhyay, Sourav Bhattacharjee +1
We study the temporal evolution of the mutual information (MI) in a one-dimensional Kitaev chain, coupled to a fermionic Markovian bath, subsequent to a global quench of the chemic…
