Unusual sound waves discovered in quantum liquids

Ordinary sound waves—small oscillations of density—can propagate through all fluids, causing the molecules in the fluid to compress at regular intervals. Now physicists have theoretically shown that in one-dimensional ...

Physicists show that superfluid light is possible

(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 example of how ...

New insight into superfluids reveals a storm at the surface

The discovery of a 'storm' layer created when superfluid helium flows across a rough surface has turned a century of understanding about one of the most important discoveries in quantum physics on its head.

X-ray laser probes tiny quantum tornadoes in superfluid droplets

An experiment at the Department of Energy's SLAC National Accelerator Laboratory revealed a well-organized 3-D grid of quantum "tornadoes" inside microscopic droplets of supercooled liquid helium – the first time this formation ...
