Quantum Spin Liquids

Beyond solids, liquids and gas, there are numerous quantum phases of mater which lie beyond classic symmetry-breaking paradigm. Quantum spin liquids (QSLs) being among them. QSLs are exotic phases of matter that can show up in some frustrated magnetic (or qubit) systems characterized by a lack of long-range magnetic order down to extremely low temperatures (unlike with conventional magnets) due to strong quantum fluctuations.

In addition to this negative definition, QSLs are also characterized by some global invariant, known as topological entanglement, emergent abelian or non-abelian quasi-particles with fractionalized statistics, and ground state degeneracy connected with emergent gauge theories.
