Quantum liquid becomes solid when heated

Phys.org  April 18, 2023 Raising the temperature of a material enhances the thermal motion of particles. Such an increase in thermal energy commonly leads to the melting of a solid into a fluid and eventually vaporizes the liquid into a gaseous phase of matter. Studying finite-temperature physics of dipolar quantum fluids, an international team of researchers (Denmark, Austria, Spain) found a surprising deviation from this general phenomenology. They described how heating a dipolar superfluid from near-zero temperatures can induce a phase transition to a supersolid state with a broken translational symmetry. They discussed the observation of this effect in experiments […]
