Eikonal Expansion for Classical Gluon Fields: from Weak to Strong
Shane Brown, Alex DeBrizzi, Alex Kovner
We develop a formal procedure of eikonal expansion for classical fields in gluodynamics. We show that in the weak field limit the expansion is straightforward and determines the ei…
Variational analysis of the deconfinement phase transition
I. I. Kogan, A. Kovner, J. G. Milhano
We study the deconfining phase transition in 3+1 dimensional pure SU(N) Yang-Mills theory using a gauge invariant variational calculation. We generalize the variational ansatz of P…
Spatial 't Hooft loop, hot QCD and Z_N domain walls
C. Korthals-Altes, A. Kovner, M. Stephanov
We show that the deconfinement phase transition in the pure Yang-Mills theory can be characterized by the change of behaviour the spatial 't Hooft loop, V(C). In the confining phas…
Sphaleron Transition Rate in Presence of Dynamical Fermions
A. Kovner, A. Krasnitz, R. Potting
We investigate the effect of dynamical fermions on the sphaleron transition rate at finite temperature for the Abelian Higgs model in one spatial dimension. The fermion degrees of…
The Two Phases of Topologically Massive Compact Theory
Ian I. Kogan, Alex Kovner
The mean field like gauge invariant variational method formulated recently, is applied to a topologically massive QED in 3 dimensions. We find that the theory has a phase transitio…
Gluon Production at High Transverse Momentum in the McLerran-Venugopalan Model of Nuclear Structure Functions
Alex Kovner, Larry McLerran, Heribert Weigert
We consider the production of high transverse momentum gluons in the McLerran-Venugopalan model of nuclear structure functions. We explicitly compute the high momentum component in…
Quantum evolution of the disoriented chiral condensates
Y. Kluger, F. Cooper, E. Mottola +2
We study the dynamics of the chiral phase transition expected during the expansion of the quark-gluon plasma produced in a high energy hadron or heavy ion collision, using the $O(4…
Gluon Production from Non-Abelian Weizsäcker-Williams Fields in Nucleus-Nucleus Collisions
Alex Kovner, Larry McLerran, Heribert Weigert
We consider the collisions of large nuclei using the theory of McLerran and Venugopalan. The two nuclei are ultra-relativistic and sources of non-abelian Weizsäcker-Williams fields…
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…
Fermionic Operators from Bosonic Fields in 3+1 Dimensions
A. Kovner, B. Rosenstein
We present a construction of fermionic operators in 3+1 dimensions in terms of bosonic fields in the framework of . The basic bosonic variables are the electric fields …
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…
Statistical Mechanics of Kinks in (1+1)-Dimensions: Numerical Simulations and Double Gaussian Approximation
Francis J. Alexander, Salman Habib, Alex Kovner
We investigate the thermal equilibrium properties of kinks in a classical $\F^4$ field theory in dimensions. From large scale Langevin simulations we identify the temperature…

We extend the bosonization of - dimensional QED with one fermionic flavor performed previously to the case of QED with an induced Chern - Simons term. The coefficient of this…

We perform the complete bosonization of 2+1 dimensional QED with one fermionic flavor in the Hamiltonian formalism. The Fermi operators are explicitly constructed in terms of the v…
A Candidate for Exact Continuum Dual Theory for Scalar QED
A. Kovner, P. Kurzepa, B. Rosenstein
We discuss a possible exact equivalence of the Abelian Higgs model and a scalar theory of a magnetic vortex field in 2+1 dimensions. The vortex model has a current - current intera…

New Look at QED: the Photon as a Goldstone Boson and the Topological Interpretation of Electric Charge
A. Kovner, B. Rosenstein
We develop the dual picture for Quantum Electrodynamics in 3+1 dimensions. It is shown that the photon is massless in the Coulomb phase due to spontaneous breaking of the magnetic…
