Analytic results for mixed O(N)-RPN-1 σ-models in two dimensions

Sergio Caracciolo, Andrea Pelissetto, Alan D. Sokal

    Research output: Contribution to journalArticlepeer-review


    We consider the two-dimensional O(N)-invariant lattice σ-model with mixed isovector-isotensor Hamiltonian. We discuss the perturbative expansion and the 1/N limit.
