Dissipation stabilizes Dicke Time Quasicrystals
Sk Anisur, Sayan Choudhury, Shuva Mondal +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…

Directional quantum walks of two bosons on the Hatano-Nelson lattice
Sk Anisur, Kartik Singh, Sayan Choudhury
We theoretically investigate the interplay of interactions and non-Hermiticity in the dynamics of two bosons on the one-dimensional Hatano-Nelson lattice with non-reciprocal tunnel…

Quasi-Discrete Time Crystals in the quasiperiodically driven Lipkin-Meshkov-Glick model
Sk Anisur, W. Vincent Liu, Sayan Choudhury
A discrete time crystal (DTC) is a remarkable non-equilibrium phase of matter characterized by the persistent sub-harmonic oscillations of physical observables in periodically driv…
