Entropy production is a key quantity in any finite-time thermodynamic process. It is intimately
tied with the fundamental laws of thermodynamics, embodying a tool to extend …

The seminal work by Sadi Carnot in the early nineteenth century provided the blueprint of a
reversible heat engine and the celebrated second law of thermodynamics eventually …

Thermodynamics originated in the need to understand novel technologies developed by the
Industrial Revolution. However, over the centuries, the description of engines, refrigerators …

Heat engines convert thermal energy into mechanical work both in the classical and
quantum regimes. However, quantum theory offers genuine non-classical forms of energy …

Quantum technologies are currently the object of high expectations from governments and
private companies, as they hold the promise to shape safer and faster ways to extract …

A quantum thermal machine is an open quantum system coupled to hot and cold thermal
baths. Thus, its dynamics can be well understood using the concepts and tools from non …

Quantum heat engines are subjected to quantum fluctuations related to their discrete energy
spectra. Such fluctuations question the reliable operation of thermal machines in the …

In the standard quantum theory, the causal order of occurrence between events is
prescribed, and must be definite. This has been maintained in all conventional scenarios of …

Physical systems close to a quantum phase transition exhibit a divergent susceptibility,
suggesting that an arbitrarily high precision may be achieved by exploiting quantum critical …

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 …
