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 …

The theory of bipartite entanglement shares profound similarities with thermodynamics. In
this Letter we extend this connection to multipartite quantum systems where entanglement …

We propose a quantum harmonic oscillator measurement engine fueled by simultaneous
quantum measurements of the noncommuting position and momentum quadratures of the …

The possibility of efficiently converting heat into work at the microscale has triggered an
intense research effort to understand quantum heat engines, driven by the hope of quantum …

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 …

The quantum battery capacity is introduced in this Letter as a figure of merit that expresses
the potential of a quantum system to store and supply energy. It is defined as the difference …

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 …

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 …

We put forth the concept of quantum noise sensing in nonlinear two-mode interferometers
coupled to mechanical oscillators. These autonomous machines are capable of sensing …
