Spin liquids: an exotic quantum state of matter | KurzweilAI: The researchers found a “kaleidoscope” of phases that represent the lowest-energy states that are allowed given the magnetic interactions... a change in the strengths of the interactions among the spins (the J1 and J2 parameters) results in different phases. For example, one simple solution is an antiferromagnet, where the spins are anti-aligned.
But one phase turns out to be a true quantum spin liquid having no order at all. When J2 is between about 21% and 36% of the value of J1, frustration coaxes the spins into disorder; the entire sample co-exists in millions of quantum states simultaneously.
