Supersolidity – A State of Matter

Supersolidity – A State of Matter

It was predicted five decades ago that Supersolidity – a state of Matter could exist. Supersolidity is a state of matter where Superfluidity and Crystalline order coexist. A supersolid is a counterintuitive phase of matter that combines the global phase coherence of a superfluid with a crystal-like self-modulation in space.


In the year 2017, two teams of Physicists from MIT and ETH Zurich independently turned a Bose-Einstein Condensate into a Supersolid. In 2019, Physicists at University of Innsbruck experimentally realized the Supersolid state. They used quantum gases of highly magnetic Lanthanide atoms.

Researchers in Quantum Optics suggest the following. “Quantum effects can cause a very cold gas of atoms to spontaneously develop both crystalline order and particle flow. That is something like a solid crystal and like a superfluid quantum liquid, a fluid flowing without friction”.

A theoretical Physicist at the University of Geneva says “A Dipolar Supersolid can be imagined as a chain of Quantum Droplets which communicate with each other via a superfluid background bath”.

Born and brought up in Kerala, I did my schooling in Kerala and graduated (B.Sc Physics) from the Calicut University. I have worked with a Swedish Company from 1994 to 2015, as a Senior Project Manager in their Group IT Division in Dubai. This blog is the result of my strong desire to communicate with others, sharing what I know and what I could gather from various sources.
