Notes on the Schwinger model: regularization and gauge invariance
the Schwinger model regularization and gauge invariance Mathematical Physics
2012/6/21
The point-splitting computation of the gauge invariant Hamiltonian for the Schwinger model on the circle in a positive energy representation is presented.
Covariant Mickelsson-Faddeev extensions of gauge and diffeomorphism algebras
Covariant Mickelsson-Faddeev extensions of gauge diffeomorphism algebras Mathematical Physics
2012/5/31
We construct new extensions of current and diffeomorphism algebras in N>3 dimensions, which are related to the Mickelsson-Faddeev algebra. The result is compatible with Dzhumadil'daev's classification...
Simplicial gauge theory and quantum gauge theory simulation
Lattice gauge theory QCD Finite element method
2011/9/29
Abstract: We propose a general formulation of simplicial lattice gauge theory inspired by the finite element method. Numerical tests of convergence towards continuum results are performed for several ...
One-loop Renormalized Coefficient of Noncommutative Supersymmetric Yang-Mills-Chern-Simons Gauge Theories in Three Dimensions
One-loop Renormalized Coefficient Noncommutative Supersymmetric Yang-Mills-Chern-Simons Gauge Theories
2011/7/28
Abstract: Recent studies of the $AdS_4/CFT_3$ correspondence involve the construction of a peculiar supersymmetric gauge theory on the worldvolume of multiple M2s branes as a boundary field theory. Un...
Homotopical Poisson reduction of gauge theories
Homotopical Poisson reduction gauge theories Algebraic Geometry
2011/7/26
Abstract: The classical Poisson reduction of a given Lagrangian system with (local) gauge symmetries has to be done before its quantization. We propose here a coordinate free and self-contained mathem...

Non-Abelian Vortices in Supersymmetric Gauge Field Theory via Direct Methods
Non-Abelian Vortices Supersymmetric Gauge Field Theory High Energy Physics - Theory
2011/7/27
Abstract: Vortices in supersymmetric gauge field theory are important constructs in a basic conceptual phenomenon commonly referred to as the dual Meissner effect which is responsible for color confin...
Entropy Production in Gluodynamics in temporal axial gauge in 2+1 dimensions
Entropy Production Gluodynamics temporal axial gauge 2+1 dimensions
2011/1/7
Entropy production in non-Abelian gauge theory is discussed in the limit of vanishing classical fields. Based on the Kadanoff-Baym equation with the leading order self-energy in
the temporal axial ga...
