Manuele Landini from the University of Innsbruck was part of an international team led by researchers at CNR Nanotec in Lecce, Italy, that has demonstrated the emergence of a supersolid phase of matter in a photonic crystal polariton condensate. This pioneering work, published in Nature, introduces a new platform for exploring supersolidity beyond traditional ultracold atomic systems. A supersolid is a rare and counterintuitive phase of matter that uniquely combines the rigidity of a crystal wit...
