SU(N)→ SU(2) symmetry breaking in quantum antiferromagnets

SU(N)→ SU(2) symmetry breaking in quantum antiferromagnets

We study a SU(2)-symmetric spin-3/2 system on a bipartite lattice close to the antiferromagnetic SU(4)-symmetric point, which can be described by the CP3 model with a perturbation breaking the symmetry from SU(4) down to SU(2) and favoring the Néel ordering. We show that the effective theory of the...
