Chaos assisted many-body tunnelling
Urbashi Satpathi, Sayak Ray, Amichay Vardi
We study the interplay of chaos and tunnelling between two weakly-coupled Bose-Josephson junctions. The classical phase space of the composite system has a mixed structure includin…
Classical route to ergodicity and scarring phenomena in a two-component Bose-Josephson junction
Debabrata Mondal, Sudip Sinha, Sayak Ray +2
We consider a Bose-Josephson junction (BJJ) formed by a binary mixture of ultracold atoms to investigate the manifestation of coherent collective dynamics on ergodicity and quantum…
Quantum signatures in quench from chaos to superradiance
Sayak Ray, Amichay Vardi, Doron Cohen
The driven-dissipative Dicke model features normal, superradiant, and lasing steady-states that may be regular or chaotic. We report quantum signatures of chaos in a quench protoco…
