Scientists discovered new form of matter,’excitonium’

A new form of matter discovered 50 years after it was first theorized, and the new form is known as ‘excitonium’. The existence of excitonium has been theorised for 50 years. Some scientists have suggested the new form might be a ‘superfluid’, that is a substance that flows easily with no friction,or it might may be an insulator, meaning it doesn’t flow at all. The credit goes to researchers at the University of Illinois for their exciting finding of the discovery of a new form of matter: excitonium.

“This result is of cosmic significance,” says Professor Peter Abbamonte, a physicist at the University of Illinois at Urbana-Champaign who led the study and published in Science. This material is made up of a kind of boson, a composite particle that could allow the matter to act as a superfluid, superconductor, or even as an insulating electronic crystal. The researchers at the University of Illinois at Urbana-Champaign studied non-doped crystals of transition metal chalcogenide, titanium diselenide. They reproduced the results five times on different cleaved crystals. University of Amsterdam Professor of Physics Jasper van Wezel provided crucial theoretical interpretation of the experimental results.
