Helium was discovered to possess superfluid characteristics at low temperatures in 1936—helium atoms flowed through extremely narrow channels without friction or viscosity. Some atomic gases can ...

Cool stuff: an experiment done by Samuli Autti (right) and colleagues at Lancaster University has shed new light on the mechanical properties of superfluid helium-3. (Courtesy: Mike Thompson) For the ...

Domain walls: MRI image of superfluid helium-3 where the boundaries between regions of different chirality appear as dark vertical lines. (Courtesy: J Kasai et al/Phys. Rev. Lett.) Topological domains ...

In a new study published in Nature Physics, researchers have developed the first controlled method for exciting and observing ...

When stirred with a rod, superfluid 3 He carries the generated heat away along the surfaces of the container. The bulk of the superfluid behaves like a vacuum and remains entirely passive. Dr ...

This is the case of helium, which can be a superfluid: a liquid that flows without losing any kinetic energy. An interesting consequence of that is that a superfluid in an open container will ...

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 ...

Researchers from Lancaster University in the UK have discovered how superfluid helium 3 He would feel if you could put your hand into it. The interface between the exotic world of quantum physics ...
