Recent years have seen tremendous progress in the theoretical understanding of quantum
systems driven dissipatively by coupling to different baths at their edges. This was possible …

Heat engines convert thermal energy into mechanical work and generally involve a large
number of particles. We report the experimental realization of a single-atom heat engine. An …

The study of open quantum systems often relies on approximate master equations derived
under the assumptions of weak coupling to the environment. However when the system is …

We demonstrate that a thermal transistor can be made up with a quantum system of three
interacting subsystems, coupled to a thermal reservoir each. This thermal transistor is …

A general thermodynamic framework is presented for open quantum systems in fixed contact
with a thermal reservoir. The first and second law are obtained for arbitrary system-reservoir …

Nonequilibrium molecular dynamics (NEMD) simulations on conceptual binary Lennard-
Jones systems show that the thermal conductivity (κ) of a superlattice (SL) can be …

An autonomous quantum thermal machine comprising a trapped atom or ion placed inside
an optical cavity is proposed and analysed. Such a machine can operate as a heat engine …

The Jaynes-Cummings-Hubbard (JCH) model is a fundamental many-body model for light-
matter interaction. As a leading platform for quantum simulation, the trapped ion system has …

Bose-Einstein condensation, the macroscopic occupation of a single quantum state,
appears in equilibrium quantum statistical mechanics and persists also in the hydrodynamic …

We study the effect of ultrastrong coupling on the transport of heat. In particular, we present a
condition for optimal rectification, ie, flow of heat in one direction and complete isolation in …
