High to low temperature: O(N) model at large N
Abstract We study the O(N) vector model for scalars with quartic interaction at large N on S 1 × S 2 without the singlet constraint. The non-trivial fixed point of the model is described by a thermal mass satisfying the gap equation at large N. We obtain the free energy and the energy density for th...
