India, March 6 -- Researchers in Italy have achieved a milestone by creating a special type of solid from light for the first time. The new solid, called 'supersolid, flows like a fluid and will help researchers better understand exotic quantum states of matter.

Researcher Daniele Sanvitto of Italy's National Research Council (CNR) had shown more than a decade ago how light could become a fluid. However, with the recent achievement, Sanvitto and his colleagues have used light to make a quantum 'supersolid'.

According to the University of Stuttgart, a supersolid is a state of matter that is both solid and liquid at the same time. According to a research, if matter is cooled to extremely low temperatures, quantum effects can enable states...
