“Second sound is the hallmark of superfluidity, but in ultracold gases so far you could only see it in this faint reflection ...

With properties of a superfluid but with a crystalline structure, supersolids have previously only been observed in ultracold ...

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 ...

Scientists have achieved a breakthrough in quantum physics, successfully creating a supersolid state using light for the ...

Scientists have transformed light into a supersolid for the first time, unlocking new possibilities in quantum physics, ...

Superconducting materials are similar to the carpool lane in a congested interstate. Like commuters who ride together, electrons that pair up can bypass the regular traffic, moving through the ...

This phenomenon occurs in certain quantum fluids, such as liquid helium-4 below a critical temperature of 2.17 K (-270.98 °C). In the superfluid state, the fluid can flow through narrow channels ...

In everyday materials, heat usually behaves predictably —it spreads outward from a hot source until it evenly distributes.

A supersolid has an ordered structure like a solid but can also flow without friction like a superfluid, and previously they have only been produced in so-called "Bose–Einstein condensates ...
