Interacting N-vector order parameters with O(N) symmetry
We consider the critical behavior of the most general system of two N-vector 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) otimes O(N) fixed point. For N=2,3,4, if the system is also invariant under t...
