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…

Black-hole powered quantum coherent amplifier
Avijit Misra, Pritam Chattopadhyay, Anatoly Svidzinsky +2
Atoms falling into a black hole (BH) through a cavity are shown to enable coherent amplification of light quanta powered by the BH gravitational vacuum energy. This process can har…

Towards Nonlinear Quantum Thermodynamics
Gershon Kurizki, Nilakantha Meher, Avijit Misra +2
We have recently put forth several schemes of unconventional, nonlinearly-enabled thermodynamic (TD) devices that can operate in either the classical or the quantum domain by trans…
