Âé¶¹ÒùÔºicists capture first sounds of heat 'sloshing' in a superfluid, revealing how heat can move like a wave

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, moving back and forth somewhat like a sound wave ...

Team shows how uranium ditelluride continues superconducting even in high magnetic fields

Superconductivity is well understood in so-called "conventional" superconductors. More recent, however, are unconventional superconductors, and it is as yet unclear how they work.
