Interacting N-vector order parameters with O(N) symmetry

We consider the critical behavior of the most general system of two Nvector order parameters that is O(N) invariant. We show that it may have a multicritical transition with enlarged symmetry controlled by the chiral O(2) ⊗ O(N) fixed point. For N = 2, 3, 4, if the system is also invariant under...
