Double scaling limit for matrix models with non analytic potentials
نویسنده
چکیده
We study the double scaling limit for unitary invariant ensembles of randommatrices with non analytic potentials and find the asymptotic expansion for the entries of the corresponding Jacobi matrix. Our approach is based on the perturbation expansion for the string equations. The first order perturbation terms of the Jacobi matrix coefficients are expressed through the Hastings-McLeod solution of the Painleve II equation. The limiting reproducing kernel is expressed in terms of solutions of the Dirac system of differential equations with a potential defined by the first order terms of the expansion.

متن کاملThe Continuous Series of Critical Points of the Two-matrix Model at N → ∞ in the Double Scaling Limit
The critical points of the continuous series are characterized by two complex numbers l1,2(Re(l1,2) < 0), and a natural number n(n ≥ 3) which enters the string susceptibility constant through γ = −2 n−1 . The critical potentials are analytic functions with a convergence radius depending on l1 (or l2). We use the orthogonal polynomial method and solve the SchwingerDyson equations with a techniqu...
متن کاملDouble Scaling Limit in the Random Matrix Model: The Riemann-Hilbert Approach
We prove the existence of the double scaling limit in the unitary matrix model with quartic interaction, and we show that the correlation functions in the double scaling limit are expressed in terms of the integrable kernel determined by the ψ function for the Hastings-McLeod solution to the Painlevé II equation. The proof is based on the Riemann-Hilbert approach, and the central point of the p...
متن کاملOn the critical behaviour of hermitean f - matrix models in the double scaling limit with f ≥ 3
An algorithm for the isolation of any singularity of f -matrix models in the double scaling limit is presented. In particular it is proved by construction that only those universality classes exist that are known from 2-matrix models.

We report about two new rigorous results on the non-analytic properties of thermodynamic potentials at first order phase transition. The first one is valid for lattice models (d ≥ 2) with arbitrary finite state space, and finite-range interactions which have two ground states. Under the only assumption that the Peierls Condition is satisfied for the ground states and that the temperature is suf...
