The laws of thermodynamics state that heat naturally flows from hotter systems or regions to colder systems or regions until a state of thermal equilibrium is reached. This simple principle underpins ...

A study published in Physical Review Letters (PRL) details a "Gambling Carnot Engine" that researchers report can attain 100% efficiency while also improving power generation. The researchers present ...

Heat has always been something we thought we understood. From baking bread to running engines, the idea seemed simple: heat spreads out smoothly, like water soaking through a sponge. That simple ...

An atom in a cavity between two mirrors (left) acts as a heat engine in a driven-dissipative quantum system in which energy ...

Researchers at the Chinese Academy of Sciences developed a thermoacoustic Stirling heat pump prototype that offers high thermal performance, a peak coefficient of performance of 1.68, and potential ...
