A Renormalization Group Study of Helimagnets in D=2+EPSILON Dimensions

P. Azaria, B. Delamotte, F. Delduc +1

We study a non linear sigma model $O(N)\otimes O(2)/O(N-2)\otimes O(2)$ describing the phase transition of N-components helimagnets up to two loop order in $D=2+\epsilon$ dimensions. It i…
