Quantum transitions, ergodicity, and quantum scars in the coupled top model
Debabrata Mondal, Sudip Sinha, S. Sinha
We consider an interacting collective spin model known as coupled top (CT), exhibiting a rich variety of phenomena related to quantum transitions, ergodicity, and formation of quan…
Dynamical route to ergodicity and quantum scarring in kicked coupled top
Debabrata Mondal, Sudip Sinha, Subhasis Sinha
Unlike classical system, understanding ergodicity from phase space mixing remains unclear for interacting quantum systems due to the absence of phase space trajectories. By conside…
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…
