Quantum engines and refrigerators

LM Cangemi, C Bhadra, A Levy - Physics Reports, 2024 - Elsevier
Engines are systems and devices that convert one form of energy into another, typically into
a more useful form that can perform work. In the classical setup, physical, chemical, and …

Thermodynamic signatures of genuinely multipartite entanglement

S Puliyil, M Banik, M Alimuddin - Physical Review Letters, 2022 - APS
The theory of bipartite entanglement shares profound similarities with thermodynamics. In
this Letter we extend this connection to multipartite quantum systems where entanglement …

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 …

Two-stroke quantum measurement heat engine

MS Alam, BP Venkatesh - arXiv preprint arXiv:2201.06303, 2022 - arxiv.org
We propose and analyze the theoretical model for a two-stroke quantum heat engine with
one of the heat baths replaced by a non-selective quantum measurement. We show that the …
