Periodically driven many-body quantum battery
Saikat Mondal, Sourav Bhattacharjee
We explore the charging of a quantum battery based on spin systems through periodic modulation of a transverse-field like Ising Hamiltonian. In the integrable limit, we find that r…
Detecting topological phase transitions through entanglement between disconnected partitions in a Kitaev chain with long-range interactions
Saikat Mondal, Souvik Bandyopadhyay, Sourav Bhattacharjee +1
We explore the behaviour of the disconnected entanglement entropy (DEE) across the topological phases of a long range interacting Kitaev chain where the long range interactions dec…
Quasi-localization dynamics in a Fibonacci quantum rotor
Sourav Bhattacharjee, Souvik Bandyopadhyay, Amit Dutta
We analyze the dynamics of a quantum kicked rotor (QKR) driven with a binary Fibonacci sequence of two distinct drive amplitudes. While the dynamics at low drive frequencies is fou…
Driven quantum many-body systems and out-of-equilibrium topology
Souvik Bandyopadhyay, Sourav Bhattacharjee, Diptiman Sen
In this review we present some of the work done in India in the area of driven and out-of-equilibrium systems with topological phases. After presenting some well-known examples of…
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…
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…
