Dissipation stabilizes Dicke Time Quasicrystals
Sk Anisur, Shuva Mondal, Tanaya Ray +1
Quasi-periodic driving protocols provide a powerful route to realize novel non-equilibrium phases of matter beyond the Floquet paradigm. However, these protocols inevitably lead to…

Entanglement marker for lifetime of time crystal in transmon-modulated open Dicke model
Tanaya Ray, Shuva Mondal, Ujjwal Sen
We investigate the discrete time crystal (DTC) phase in a qubit ensemble, periodically driven by its interaction with either a photon or a transmon field, which is prone to dissipa…

Kerr-type nonlinear baths enhance cooling in quantum refrigerators
Tanaya Ray, Sayan Mondal, Aparajita Bhattacharyya +3
We study the self-contained three-qubit quantum refrigerator, with a three-body interaction enabling cooling of the target qubit, in presence of baths composed of anharmonic quantu…
