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…
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…
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…
Work extraction from single-mode thermal noise by measurements: How important is information?
Avijit Misra, Tomas Opatrný, Gershon Kurizki
Our goal in this article is to elucidate the rapport of work and information in the context of a minimal quantum mechanical setup: A converter of heat input to work output, the inp…
Quantum Superposition of Two Temperatures
Arun Kumar Pati, Avijit Misra
In the classical world, temperature is a measure of how hot or cold a physical object is. We never find a physical system which can be both hot and cold at the same time. Here, we…
Nonlinear coherent heat machines and closed-system thermodynamics
Tomáš Opatrný, Šimon Bräuer, Abraham G. Kofman +5
All existing heat machines are dissipative open systems. Hence, they cannot operate fully coherently. We propose to replace this conventional thermodynamic paradigm by a completely…
