Researchers have found evidence of a theorized quantum phenomenon, quantum spin liquid, in a material called pyrochlore cerium stannate.
A team of researchers from Switzerland and France and theoretical physicists in Canada and the U.S., including Rice University, believe they have found evidence of a theorized quantum phenomenon called quantum spin liquid. Observed in a material called pyrochlore cerium stannate, this discovery could yield discoveries in fundamental physics and open doors to breakthroughs in other things like quantum computers.
According to the theory, these spins can stay in constantly changing, interconnected states that behave oddly, similar to those inHowever, proving the theory has, until now, proved very challenging. To this end, the international team developed advanced experiments and theoretical models to attempt to observe this state of matter for the first time.
“Neutron scattering is a well-established tool in analyzing the behavior of spins in magnets,” added Andriy Nevidomskyy, associate professor of physics and astronomy at Rice, who conducted a theoretical analysis of the acquired data. “It is challenging, however, to develop an unambiguous ‘smoking gun’ signature that would prove the material harbors a quantum spin liquid,” he added.
When electrons interact, their “spins” align or anti-align . However, this alignment/anti-alignment can be disrupted in some materials, like
