Physicists discover new state of matter called quantum spin liquid

Researchers from Switzerland, France, Canada, and the U.S. have found evidence of a new state of matter called quantum spin liquid in a material known as pyrochlore cerium stannate. This state features magnetic particles that do not settle into a fixed pattern. The team used advanced experiments, including neutron scattering, to observe this phenomenon for the first time. They achieved high-resolution data that supports the existence of fractional matter quasiparticles, which were previously theorized. The discovery opens avenues for exploring other exotic particles and could enhance understanding of fundamental physics and quantum mechanics. The findings are published in the journal Nature Physics.
