Context: Italian scientists have demonstrated that light can exist as a supersolid, combining solid-like structure with frictionless flow.

About Supersolid light:

• What is Supersolid Light?

• Supersolid light is a rare quantum state where light exhibits both the rigid structure of a solid and the frictionless flow of a superfluid.

• Previously, supersolidity had only been observed in Bose-Einstein condensates(BECs) a state of matter that forms when a collection of bosons is cooled to nearly absolute zero, causing them to share the same quantum state.

• How is Supersolid Light Formed?

• Platform Used: Researchers used a semiconductor gallium arsenide structure embedded with microscopic ridges. Creation of Polaritons: By firing a laser, they generated polaritons — hybrid particles made from light and matter. Observation of Satellite Condensates: As the photon count increased, satellite condensates appeared, showing symmetric energy but opposite wavenumbers — a key indicator of supersolidity.
