Physicists have observed a strange new quantum phase in a graphene-based system, where a superfluid appears to freeze into a solid-like state. Cooling usually pushes matter through a simple sequence.

When everyday matter is cooled, it follows a familiar path. A gas becomes a liquid, and with further cooling, that liquid turns into a solid. Quantum ...

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 ...

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, ...

A complementary approach is to swap the helium gas for liquid helium, which has a much higher density. Sótér and colleagues found that this method could be used to measure very narrow lines in the ...
