Transient and steady-state chaos in dissipative quantum systems
Debabrata Mondal, Lea F. Santos, S. Sinha
Dissipative quantum chaos plays a central role in the characterization and control of information scrambling, non-unitary evolution, and thermalization, but it still lacks a precis…
Supersolid phases of bosons
Sudip Sinha, S. Sinha
Supersolids--the enigmatic phase of quantum matter, with properties resembling both the superfluid and solid states--have been actively sought over the past 70 years. We provide a…
Exploring the properties of quantum scars in a toy model
Sudip Sinha, S. Sinha
We introduce the concept of ergodicity and explore its deviation caused by quantum scars in an isolated quantum system, employing a pedagogical approach based on a toy model. Quant…
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…
