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 …

Quantum information theory is built upon the realisation that quantum resources like
coherence and entanglement can be exploited for novel or enhanced ways of transmitting …

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 …

Near-field radiative heat transfer has recently attracted increasing interests for its
applications in energy technologies, such as thermophotovoltaics. Existing works, however …

The extension of thermodynamics into the quantum regime has received much attention in
recent years. A primary objective of current research is to find thermodynamic tasks which …

An implementation of a small quantum absorption refrigerator in a circuit QED architecture is
proposed. The setup consists of three harmonic oscillators coupled to a Josephson junction …

Nonequilibrium effects may have a profound impact on the performance of thermal devices
performing thermodynamic tasks such as refrigeration or heat pumping. The possibility of …

In classical thermodynamics energy always flows from the hotter system to the colder one.
However, if these systems are initially correlated, the energy flow can reverse, making the …

The thermodynamic uncertainty relation, originally derived for classical Markov-jump
processes, provides a tradeoff relation between precision and dissipation, deepening our …
