Fingerprint of chaos and quantum scars in kicked Dicke model: An out-of-time-order correlator study
Sudip Sinha, Sayak Ray, Subhasis Sinha
We investigate the onset of chaos in a periodically kicked Dicke model (KDM), using the out-of-time-order correlator (OTOC) as a diagnostic tool, in both the oscillator and the spi…
Chaos and quantum scars in a coupled top model
Debabrata Mondal, Sudip Sinha, S. Sinha
We consider a coupled top model describing two interacting large spins, which is studied semiclassically as well as quantum mechanically. This model exhibits variety of interesting…
Chaos and quantum scars in Bose-Josephson junction coupled to a bosonic mode
Sudip Sinha, S. Sinha
We consider a model describing Bose-Josephson junction (BJJ) coupled to a single bosonic mode exhibiting quantum phase transition (QPT). Onset of chaos above QPT is observed from s…
Dissipative Bose-Josephson junction coupled to bosonic baths
Sudip Sinha, S. Sinha
We investigate the effect of dissipation in a Bose-Josephson junction (BJJ) coupled to bath of bosons at two sites. Apart from the dynamical transition due to repulsive interaction…
