Unitary Multiperipheral Models*
The method of constructing unitary S-matrices developed in a recent paper is generalized and applied to two versions of the multiperipheral model. In these models the standard perturbation expansion of the S-matrix diverges, so an alternative expansion with improved convergence properties is developed. It is shown that the unitarity condition generates a new type of cut in the angular momentum ...
متن کاملLocal models for ramified unitary groups
S′ −−−−→ Spec(OE) is cartesian. To qualify as a model, the scheme S′ should at least be flat over Spec(OE) and have only “good” singularities. In the PEL-case, S can be written as a moduli space of abelian varieties with polarization, an action by a semisimple Q-algebra and a K-level strucure where K ⊂ G(Af ) is an open and compact subgroup. If we fix a prime p , the investigation of a model S′...
متن کاملUnitary Matrix Models and Painlevé III
We discussed relations between the full unitary matrix models and the Painlevé III. Coupling the Toda equations and the string equations, we derive a special case of the P III equation. From the Virasoro constrains, we can use the radial coordinate. The relation between t1 and t−1 is like the complex conjugate.
متن کاملUnitary Matrix Models and Phase Transition
We study the unitary matrix model with a topological term. We call the topological term the theta term. In the symmetric model there is the phase transition at λc = 2. If the Wilson term is larger than the theta term, there is the phase transition at the same λc. On the other hand, if the theta term is larger than the Wilson term, there is no phase transition.
متن کاملLyapunov Exponents for Unitary Anderson Models
We study a unitary version of the one-dimensional Anderson model, given by a five diagonal deterministic unitary operator multiplicatively perturbed by a random phase matrix. We fully characterize positivity and vanishing of the Lyapunov exponent for this model throughout the spectrum and for arbitrary distributions of the random phases. This includes Bernoulli distributions, where in certain c...
