Light has been transformed into a ‘supersolid’ for the first time
Supersolids are strange materials that behave like both a solid and a fluid due to quantum effects – and now researchers have created an intriguing new type of supersolid from laser light
Sanvitto says the team had to very precisely measure enough properties of this trapped and transformed light to prove it was both a solid and a fluid with no viscosity. The new experiment contributes to physicists’ general understanding of how quantum matter can change its state by going through a phase transition, says Alberto Bramati at Sorbonne University in France. Trypogeorgos says light-based supersolids may be easier to manipulate than those previously created with atoms, which could make his team’s experiment a first step towards understanding a slew of novel and surprising types of matter.
