The significance of this breakthrough extends beyond superfluid helium. The validated S2W model holds promise for applications in other quantum-fluid systems, such as atomic Bose-Einstein condensates ...

Over the past few decades, some physicists worldwide have been trying to use the second layer of 4 He films adsorbed on a graphite substrate to study the interplay between superfluid and supersolid ...

Physicists at MIT have achieved a major feat, capturing a bizarre quantum effect called second sound on film, where heat ripples through matter like a wave instead of spreading gradually. First ...

Scientists from the Graduate School of Engineering Science at Osaka University used optical tweezers for the first time inside superfluid helium. With a strongly focused beam of light, they ...

We can learn a lot by studying microscopic and macroscopic changes in a material as it crosses from one phase to another, for example from ice to water to steam. A new study examines systems ...

Cool stuff: an experiment done by Samuli Autti (right) and colleagues at Lancaster University has shed new light on the mechanical properties of superfluid helium-3. (Courtesy: Mike Thompson) For the ...

Researchers have developed a new tool for measuring velocities in a Bose-Einstein condensate superfluid and applied it to studying superfluid turbulence. (Nanowerk News) Despite existing everywhere, ...

Perhaps the best-known example of hysteresis is the response of the magnetization of a ferromagnetic material to an applied magnetic field. If the material is initially unmagnetized, slowly turning on ...

In everyday life, all matter exists as either a gas, liquid, or solid. In quantum mechanics, however, it is possible for two distinct states to exist simultaneously. An ultracold quantum system, for ...

Suppose the acceleration stops to give a final steady velocity above v L. The surface excitation distributions will gradually come into equilibrium with the wire, cutting off the escape processes.

LOOK up at the sky. Almost everything out there is spinning around: stars, galaxies, planets, moons – they are all rotating. Yet physicists believe that the universe itself is not revolving. Why? It’s ...

We can learn a lot by studying microscopic and macroscopic changes in a material as it crosses from one phase to another, for example from ice to water to steam. A new Australian study examines ...
