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…
