Quantum spin liquids are difficult to explain and even harder to understand.
To start, they have nothing to do with everyday liquids, like water or juice, but everything to do with special magnets and how they spin. In regular magnets, when the temperature drops, the spin of the electrons essentially freezes and forms a solid piece of matter. In quantum spin liquids, however, the spin of electrons doesn't freeze—instead the electrons stay in a constant state of flux, as they would in a free-flowing liquid.
, a phenomenon Albert Einstein famously termed"spooky action at a distance." This is where two atoms become linked and able to exchange information no matter how far apart they are. In quantum spin liquids, disorder introduces discrepancies that essentially butt heads with the theory behind the liquids. One prevailing explanation was that when disorder is introduced, the material ceases to be a quantum spin liquid and instead is simply a magnet that's in a state of disorder."So, the big question was whether the quantum spin liquid state survives in the presence of disorder and if it does survive, how?" Plumb said.
The findings essentially suggest that the material they looked at, which is one of the prime candidates to be a quantum spin liquid, does appear to be close to one, yet with an additional component. The researchers posit that it's a quantum spin liquid that is disordered, making it a new phase of disordered matter.
