1 Kazakov - Migdal Induced Gauge Theory
We give the exact solution of the Kazakov-Migdal induced gauge model in the case of a D=1 compactified lattice with a generic number S of sites and for any value of N. Due to the peculiar features of the model, the partition function that we obtain also describes the vortex-free sector of the D=1 compactified bosonic string, and it coincides in the continuum limit with the one obtained by Boula...
متن کاملThe Spatial Dynamics in Kazakov – Migdal Model
The spatially inhomogeneous large N solutions to Kazakov–Migdal model are analyzed. The set of nonlinear differential equations is derived in the continuum limit. In one dimensional case these equations has a natural interpretation in terms of the dynamics of a Fermi gas. The multidimensional case seems to be inconsistent because of its instability related to the collapse of eigenvalues of the ...
متن کاملStatus of the Kazakov–Migdal Model
In this talk I discuss both the present status and some recent work on the Kazakov–Migdal Model which was originally proposed as a soluble, large N realization of QCD. After a brief description of the model and a discussion of its solubility in the large N limit I discuss several of the serious problems with the model which lead to the conclusion that it does not induce QCD. The model is noneth...
متن کاملThe Spectrum of the Kazakov-Migdal Model
Gross has found an exact expression for the density of eigenvalues in the simplest version of the Kazakov-Migdal model of induced QCD. In this paper we compute the spectrum of small fluctuations around Gross’s semi-circular solution. By solving Migdal’s wave equation we find a string-like spectrum which, in four dimensions, corresponds to the infinite tower of mesons in strong coupling lattice ...
متن کاملPhase diagram of the N=2 Kazakov-Migdal model.
We have determined the phase diagram of the simplest version of a lattice model introduced in the recent work of Kazakov and Migdal. If m0 and λ are the bare mass and self coupling of the scalar field in the model respectively, we find a line of first order phase transitions in the (m0, λ) plane ending in a critical point where λ is nonzero. Kazakov and Migdal speculate that their model of scal...
