Critical behaviour of the O(n)-${\varphi }^4$ model with an antisymmetric order parameter

N. V. Antonov, M. V. Kompaniets, N. M. Lebedev

Critical behaviour of the O(n)-symmetric ${\varphi }^4$-model with an antisymmetric tensor order parameter is studied by means of the field-theoretic renormalization group (RG) in the lea…
