Hydrogen nano-clusters at low temperatures display 'superfluidity'—a quantum state of frictionless flow only previously observed in helium.

In stark contrast to a classical fluid, they concluded that the interior bulk of superfluid helium-3 would feel empty, like moving your fingers through a vacuum. Since heat is conveyed across the ...

In a new study published in Nature Physics, researchers have developed the first controlled method for exciting and observing Kelvin waves in superfluid helium-4.

Two physicists from Penn State University will announce new experimental evidence for the existence of a new phase of matter, a "supersolid" form of helium-4 with the extraordinary frictionless ...

Physicists have figured out how objects traveling through a superfluid can exceed a critical speed limit.

Superfluid light flows past obstacles without scattering Scientists show that, under the right conditions, light that can flow past … ...

Superfluid helium can do some seemingly impossible things, like climb up the walls of containers or leak through pores that are too small for normal liquid helium to pass through.

Physicists from Penn State University have new experimental evidence for the existence of a new phase of matter, a "supersolid" form of helium-4 with the extraordinary frictionless-flow properties ...

In a new study, physicists from France have theoretically shown that superfluid motion of light is indeed possible, and have proposed an experiment to observe the phenomena.
