(Pseudo-)Goldstone boson interaction in D=2+1 systems with a spontaneously broken internal rotation symmetry
The low-temperature properties of systems characterized by a spontaneously broken internal rotation symmetry, O(N)→O(N−1), are governed by Goldstone bosons and can be derived systematically within effective Lagrangian field theory. In the present study we consider systems living in two spatial dimen...
