Since a fluid transitions into a superfluid at a certain critical, ultracold temperature, the MIT team reasoned that the two types of fluid should also transport heat differently: In normal fluids ...

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 ...

MIT scientists have imaged heat traveling as a wave, called "second sound," in superfluid quantum gas. This discovery could unlock mysteries of neutron stars and superconductors.

Next, the researchers measured the diffusivity of the material, or how well it damps sound waves. This quantity, which has never previously been measured in a strongly interacting Fermi gas, gives ...

Usually, when something gets warmed up, heat tends to spread outward before eventually dissipating. But things are a little different in the world of superfluid quantum gas. For the first time ...

For the first time, physicists have captured direct images of 'second sound,' the movement of heat sloshing back and forth within a superfluid. The results will expand scientists' understanding of ...

In most materials, heat prefers to scatter. If left alone, a hotspot will gradually fade as it warms its surroundings. But in rare states of matter, heat can behave as a wave, ...
