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 tiny machine made from just an atom and particles of light may sound impossibly simple, but it raises a surprisingly ...

Researchers are developing new ways to understand energy in tiny quantum machines. They argue that escaping light may still ...

A tiny superconducting engine has successfully converted heat near absolute zero into useful work, demonstrating the first cyclic quantum heat engine of its kind. Future versions could operate ...

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 ...
