Matching Conditions and Duality in N=1 SUSY Gauge Theories in the Conformal Window
Ian I. Kogan, Mikhail Shifman, Arkady Vainshtein
We discuss duality in SUSY gauge theories in Seiberg's conformal window, . The 't Hooft consistency conditions -- the basic tool for establishing the infra…
Compact QED - a simple example of a variational calculation in a gauge theory
Ian I. Kogan, Alex Kovner
We apply a simple mean field like variational calculation to compact QED in 2+1 dimensions. Our variational ansatz explicitly preserves compact gauge invariance of the theory. We r…
A variational approach to the QCD wave functional:Dynamical mass generation and confinement
Ian I. Kogan, Alex Kovner
We perform a variational calculation in the SU(N) Yang Mills theory in 3+1 dimensions. Our trial variational states are explicitly gauge invariant, and reduce to simple Gaussian st…
Continuum Limits of ``Induced QCD": Lessons of the Gaussian Model at d=1 and Beyond
I. I. Kogan, A. Morozov, G. W. Semenoff +1
We analyze the scalar field sector of the Kazakov--Migdal model of induced QCD. We present a detailed description of the simplest one dimensional {()} model which supports…
Area Law and Continuum Limit in "Induced QCD"
I. I. Kogan, A. Morozov, G. W. Semenoff +1
We investigate a class of operators with non-vanishing averages in a D-dimensional matrix model recently proposed by Kazakov and Migdal. Among the operators considered are ``filled…
