Macroscopic loop amplitudes in the multi-cut two-matrix models
Abstract
Multi-cut critical points and their macroscopic loop amplitudes are studied in the multi-cut two-matrix models, based on an extension of the prescription developed by Daul, Kazakov and Kostov. After identifying possible critical points and potentials in the multi-cut matrix models, we calculate the macroscopic loop amplitudes in the Zk symmetric background. With a natural large N ansatz for the matrix Lax operators, a sequence of new solutions for the amplitudes in the Zk symmetric k-cut two-matrix models are obtained, which are realized by the Jacobi polynomials.
