Minimal universal quantum heat machine
David Gelbwaser-Klimovsky, Robert Alicki, Gershon Kurizki
In traditional thermodynamics the Carnot cycle yields the ideal performance bound of heat engines and refrigerators. We propose and analyze a minimal model of a heat machine that c…

Quantum bath refrigeration towards absolute zero: unattainability principle challenged
Michal Kolář, David Gelbwaser-Klimovsky, Robert Alicki +1
A minimal model of a quantum refrigerator (QR), i.e. a periodically phase-flipped two-level system permanently coupled to a finite-capacity bath (cold bath) and an infinite heat du…
