Quantum chaos in the Dicke model and its variants
Devvrat Tiwari, Subhashish Banerjee
Recently, the out-of-time-ordered correlator (OTOC) has gained much attention as an indicator of quantum chaos. In the semi-classical limit, its exponential growth rate resembles t…

Impact of non-Markovian evolution on characterizations of quantum thermodynamics
Devvrat Tiwari, Subhashish Banerjee
Here we study the impact of non-Markovian evolution on prominent characteristics of quantum thermodynamics, such as ergotropy and power. These are benchmarked by the behavior of th…
