Study of the N=2 Kazakov-Migdal model.
We study numerically the SU(2) Kazakov-Migdal model of ‘induced QCD’. In contrast to our earlier work on the subject we have chosen here not to integrate out the gauge fields but to keep them in the Monte Carlo simulation. This allows us to measure observables associated with the gauge fields and thereby address the problem of the local Z2 symmetry present in the model. We confirm our previous ...
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 کاملa study on insurer solvency by panel data model: the case of iranian insurance market
the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.
The 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 ...
