Heat-machine control by quantum-state preparation: from quantum engines to refrigerators
David Gelbwaser-Klimovsky, Gershon Kurizki
We explore the dependence of the performance bounds of heat engines and refrigerators on the initial quantum state and the subsequent evolution of their piston, modeled by a quanti…
Work and energy gain of heat-pumped quantized amplifiers
David Gelbwaser-Klimovsky, Robert Alicki, Gershon Kurizki
We investigate heat-pumped single-mode amplifiers of quantized fields in high-Q cavities based on non-inverted two-level systems. Their power generation is shown to crucially depen…
How much work can a quantum device extract from a heat engine?
D. Gelbwaser-Klimovsky, R. Alicki, G. Kurizki
Work extraction from a heat engine in a cycle by a quantum mechanical device (quantum "piston") is analyzed. The standard definition of work fails in the quantum domain. The correc…
