- Authors: Saikat Sur and Arnab Ghosh
- Abstract summary: We show that a quantum gas, a collection of massive, non-interacting, indistinguishable quantum particles, can be realized as a thermodynamic machine.
Such a thermodynamic machine depends on the statistics of the particles, the chemical potential, and the spatial dimension of the system.

- Abstract: 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 artifact of energy quantization and hence bears no
classical analog. Such a thermodynamic machine depends on the statistics of the
particles, the chemical potential, and the spatial dimension of the system. Our
detailed analysis demonstrates the fundamental features of quantum Stirling
cycles from the viewpoint of particle statistics and system dimensions that
helps us to realize desired quantum heat engines and refrigerators by
exploiting the role of quantum statistical mechanics. In particular, a clear
distinction between the behavior of a Fermi gas and a Bose gas is observed in
one dimension than in higher dimensions, solely due to the innate differences
in their particle statistics indicating the conspicuous role of a quantum
thermodynamic signature in lower dimensions.

We study a class of quantum many-body thermal machines whose operation is directly enabled by second-order atom-atom correlations in an ultracold atomic gas.
We show that operating these thermal machines in the intended regimes, such as a heat engine, refrigerator, thermal accelerator, or heater, would be impossible without such atom-atom correlations.

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 quantum regime, however, the principles of energy conversion become ambiguous, since quantum phenomena come into play.
Our work provides a broad overview of this active field of quantum engines and refrigerators, reviewing the latest theoretical proposals and experimental realizations.
