The custom machine uses an ESP32-C3, OLED display, and 16-key keypad while squeezing retro gaming into a tiny 150mW power budget.

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

A tiny quantum machine can release light that is not simply wasted heat; some of that energy may still be useful for doing work. University of Basel physicists found that separating orderly, coherent ...

A collaboration of researchers across international borders observed an anomalous thermal effect that allows quantum systems to absorb heat from cold thermal reservoirs. The team then leveraged this ...

What is heat, and what is useful work if a machine consists only of an atom and light particles? In modern quantum technologies, this kind of question connects thermodynamics with quantum physics.

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 ...
