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 …

Measurement-based quantum thermal machines are fascinating models of thermodynamic
cycles where measurement protocols play an important role in the performance and …

In this article, we show that a quantum gas, a collection of massive, non-interacting,
indistinguishable quantum particles, can be realized as a thermodynamic machine as an …

We propose heat machines that are nonlinear, coherent, and closed systems composed of
few field (oscillator) modes. Their thermal-state input is transformed by nonlinear Kerr …

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 …
