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…
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…
Bosonization of with an induced Chern - Simons term
A. Kovner, P. S. Kurzepa
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…
Fermions from photons: Bosonization of QED in 2+1 dimensions
A. Kovner, P. S. Kurzepa
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…
Bosonization in 2+1 dimensions without Chern - Simons attached
A. Kovner, P. Kurzepa
We perform the complete bosonization of 2+1 dimensional QED with one fermionic flavor in the Hamiltonian formalism. The fermion operators are explicitly constructed in terms of the…
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…
