Emergence of superradiance in dissipative dipolar-coupled spin systems
Saptarshi Saha, Yeshma Ibrahim, Rangeet Bhattacharyya
In the superradiance phenomenon, a collection of non-interacting atoms exhibits collective dissipation due to interaction with a common radiation field, resulting in a non-monotoni…

Prethermalization in an open quantum system coupled to a spatially correlated Bosonic bath
Saptarshi Saha, Rangeet Bhattacharyya
A nearly-integrable isolated quantum many-body system reaches a quasi-stationary prethermal state before a late thermalization. Here, we revisit a particular example in the setting…
