Solid research leads physicists to propose new state of matter
The term “superfluid quasicrystal” sounds like something a comic-book villain might use to carry out his dastardly plans.
In reality, it’s a new form of matter proposed by theoretical physicists at The University of Texas at Dallas in a recent study published in the journal Physical Review Letters. Their study also describes a “recipe” for making the exotic materials in the lab.
Most people are familiar with the three fundamental states of matter: solid, liquid and gas. There are actually several more, including plasma, which is found inside the sun and other stars, and Bose-Einstein condensates, which are very dense and exist only at the most extreme cold temperatures.
A superfluid is an exotic state of matter with unusual properties. It has zero viscosity, which means it can flow across a surface and not slow down—or lose any energy—due to friction with the surface. Superfluids, such as liquid helium, must be cooled to extremely low temperatures for such properties to emerge.
