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 quantum advantage: Coherent superposition in quantum heat engines can enhance power output over classical machines. Credit: iStock Traffic-Analyzer Heat engines have had a huge impact on everyday ...

Researchers have used an ensemble of NV− centers in diamond for implementing different types of quantum heat engines. They have used these to demonstrate the equivalence of the power output of two ...

Researchers at MIT have built a highly efficient thermophotovoltaic cell that, when paired with renewable resources, efficiently converts incoming photons—particles of light—to electricity. It’s an ...

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 ...

(Auburn, AL) 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 ...

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 ...
