In a breakthrough that challenges conventional physics, scientists have confirmed the existence of “second sound” — a phenomenon where heat travels as a wave rather than dispersing slowly, as it does ...

In the world of average, everyday materials, heat tends to spread out from a localized source. Drop a burning coal into a pot of water, and that liquid will slowly rise in temperature before its heat ...

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, MIT ...
