Extracting Work from Discrete Quantum Polytropic Processes
Vishal Anand, Swarup Kumar Giri, Avijit Misra +2
We establish an upper bound on extractable work for time-dependent, non-Markovian quantum heat engines operating with finite baths. This bound analytically isolates the distinct th…

Unravelling the non-Markovian spin-boson model and quantum quasi-Otto cycle
Shreyas Harshal Pradhan, Hadi Mohammed Soufy, Vishal Anand +3
We use the spin-boson model to describe the dynamics of a two-level atom interacting with Fabry-Pérot cavity modes. We solve the Schrödinger equation for the system-bath model wi…
