For two centuries, students have learned that heat flows and engines work according to rigid limits that no machine can beat.

Almost exactly 200 years ago, French physicist Sadi Carnot determined the maximum efficiency of heat engines. The Carnot ...

Physicists from Trinity College Dublin believe new insights into the behavior of light may offer a new means of solving one ...

The smaller the better, and in a world of fast-developing technology, that’s called innovation. Just this month, a desk-sized turbine capable of powering a small town was announced to be under ...

The heat engine works as its intrinsic spin converts heat absorbed from laser beams into oscillations of a trapped ion. Credit: John Goold, Trinity College Dublin A new heat engine made from a ...

In and out: An illustration of the quantum engine as a piston, showing the piston compressed when the particles in the gas exist as bosonic molecules and expanded when they are individual fermionic ...

Researchers have developed a steam engine that's only a few micrometers wide. It works - although it does sputter a bit. (Image Credit: Max Planck Society) Researchers at the Max Planck Institute have ...

For the first time, a quantum engine has outperformed its traditional equivalent, without any special tweaks to its environment. The device harnesses the weird physics of very small objects to produce ...

ACCORDING to Dr. George Saintsbury, “A review … is a thing addressed to the general body of educated people, telling them whether it is or is not worth their while to make further acquaintance with ...
