Superfluid

It took a specially designed crygoenic chamber to contain the super-chilled helium and whip up the vortex

Quantum tornado mimics black holes' warped spacetime in the lab

A giant quantum vortex has been created in superfluid helium in a lab at the University of Nottingham. Its behavior was found to mimic that of black holes and may help astrophysicists gain deeper insight into these galactic gravity gobblers.

Scientists at MIT have directly observed heat acting strangely in a superfluid

Heat caught moving like sound waves in a superfluid for first time

Scientists at MIT have directly captured signs of “second sound” in a superfluid for the first time. This bizarre phenomenon occurs when heat moves like sound waves through an unusual state of matter.

Cesium atoms get a shake-up to create excitation in superfluid

With properties that seemingly defy normal physics, Helium-4 superfluid has long defied practical demonstrations of its theorized quasiparticle structure. Now physicists claim to have synthesized this structure in a laser latticed, super-cold superfluid by giving the whole thing a good shake.
