The λ (lambda)
universality class is a group in
condensed matter physics. It regroups several systems possessing strong analogies, namely,
superfluids,
superconductors and
smectics (
liquid crystals). All these systems are expected to belong to the same universality class for the thermodynamic critical properties of the phase transition. While these systems are quite different at the first glance, they all are described by similar formalisms and their typical
phase diagrams are identical.
