Emergent prethermal Bethe integrability in a periodically driven Rydberg chain

Saptadip Roy, Arnab Sen, Diptiman Sen +1

We study a chain of periodically driven Rydberg atoms and identify a class of drive protocols for which the system exhibits emergent prethermal Bethe integrability at special drive…

Generating pairwise entanglement in periodically driven quantum spin chains with stochastic resetting

Sinchan Ghosh, Manas Kulkarni, K. Sengupta +1

We show that stochastic resetting may lead to finite entanglement between individual, spatially separated spins (pairwise entanglement) in the steady state of the spin chains drive…

Floquet scars and prethermal fragmentation in a driven spin-one chain

Krishanu Ghosh, Diptiman Sen, K. Sengupta

We study the periodic dynamics of a spin-one chain driven using a square-pulse protocol with amplitude and frequency . The Hamiltonian of the spin chain hosts a thermod…

Entanglement asymmetry in periodically driven quantum systems

Tista Banerjee, Suchetan Das, K. Sengupta

We study the dynamics of entanglement asymmetry in periodically driven quantum systems. Using a periodically driven XY chain as a model for a driven integrable quantum system, we p…

Emergent symmetries in prethermal phases of periodically driven quantum systems

Tista Banerjee, K. Sengupta

Periodically driven closed quantum systems are expected to eventually heat up to infinite temperature reaching a steady state described by a circular orthogonal ensemble (COE). How…
