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 ...

(PhysOrg.com) -- Superfluidity – the phase of matter that enables a fluid to move up the sides of its container – has been known about since the 1930s. Since then, superfluidity has become a prime ...

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 ...

Spinning around: superfluid vortices could provide an insight into their classical counterparts Quasiparticles within a rotating sample of superfluid helium-3 create unexpected friction in a material ...

Two recent experiments have highlighted the links between low-temperature physics and fluid dynamics When the pilot gives the order to fasten seat belts during a flight, and the other passengers start ...

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.

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 ...
