Physicists said they have finally experimentally documented quantum spin liquids, a long sought-after exotic state of matter. The work marks a big step toward being able to produce this elusive state on demand and to gain a novel understanding of its mysterious nature.
In 1973, physicist Philip W. Anderson theorized the existence of a new state of matter that has been a major focus of the field, especially in the race for quantum computers.
This bizarre state of matter is called a quantum spin liquid and, contrary to the name, has nothing to do with everyday liquids like water. Instead, it’s all about magnets that never freeze and the way electrons in them spin...
