While Rolf Landauer was working at IBM in the early 1960s, he had a startling insight about how heat, entropy, and information were connected. Landauer realized that manipulating information releases heat and increases entropy, ...

(Phys.org)—Before there were lasers, there were masers—devices that operate in the microwave regime and other wavelengths that are longer than those of visible light. But while the first masers were built back in the ...
Ordinarily, light particles—photons—don't interact. If two photons collide in a vacuum, they simply pass through each other.

Superconductivity is the ability of some materials to conduct a direct electrical current (DC) with almost no resistance. This property is highly sought after and favorable for various technological applications, as it could ...
In 2018, the physics world was set ablaze with the discovery that when an ultrathin layer of carbon, called graphene, is stacked and twisted to a "magic angle," that new double layered structure converts into a superconductor, ...
