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…
Emergence of a quasi-ergodic steady state in a dissipative Tavis-Cummings array
Debabrata Mondal, K. Sengupta, Subhasis Sinha
In an atom-photon interacting system described by Tavis Cummings Hubbard (TCH) model, we demonstrate the emergence of a quasi-steady state in a dissipative environment that exhibit…
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…
