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 ...
Simplicial gauge theory on spacetime
Lattice gauge theory QCD simplicial complex Yang-Mills theory Finite element method
2011/8/29
Abstract: We define a discrete gauge-invariant Yang-Mills-Higgs action on spacetime simplicial meshes. The formulation is a generalization of classical lattice gauge theory, and we prove consistency o...

Gauge theory in dimension $7$
calibrations elliptic boundary problems on manifolds G2–manifolds
2011/3/1
We first review the notion of a G2–manifold, defined in terms of a principal G2 (“gauge”)
bundle over a 7–dimensional manifold, before discussing their relation to supergravity. In a
second thread, ...
Technicolor and other theories of dynamical electroweak symmetry breaking invoke chiral symmetry breaking triggered by strong gauge-dynamics, analogous to that found in QCD, to explain the observed W,...

Haag's theorem states that if a quantum field theory is Lorentz invariant and irreducible, there is no interaction picture. But if we construct quantum field theory on a discrete lattice spacetime, it...

Perturbative improvement of SU(2) gauge theory with two Wilson fermions in the adjoint representation
Perturbative improvement SU(2) gauge theory
2011/1/6
We present a perturbative calculation of the improvement coefficients of SU(2) gauge theory with adjoint representation Wilson-clover fermions and using Schrodinger functional boundary conditions. The...

We present a perturbative calculation of the improvement coefficients of SU(2) gauge theory with adjoint representation Wilson-clover fermions and using Schrodinger functional boundary conditions. The...
Based on the earlier work [S.-S. Lee, Nucl. Rev. B 832, 567 (2010)], we derive a holographic dual for the D-dimensional U(N) lattice gauge theory from a first principle construction. The resulting the...
Exploration of the phase structure of $SU(N_c)$ lattice gauge theory with many Wilson fermions at strong coupling

2011/1/6
We explore aspects of the phase structure of SU(2) and SU(3) lattice gauge theories at strong coupling with many flavours $N_f$ of Wilson fermions in the fundamental representation, including the rele...
The sphaleron rate is defined as the diffusion constant for topological number NCS = int g^2 F Fdual/32 pi^2. It establishes the rate of equilibration of axial light quark number in QCD and is of inte...

2011/1/6
We present our preliminary study of the SU(2) gauge theory with 8 flavors of fermions in fundamental representation. This theory could be a candidate of the gauge theory with conformal fixed point. By...
There are no Static Solutions in Source-Free Non-commutative $U_{\star}(1)$ Gauge Theory
Static Solutions Source-Free Non-commutative
2010/12/24
The vanishing of self-stress for static systems excludes finite energy time-independent solutions of source-free $U_{\star}(1)$ theory in (3+1) dimensions. This implies that static solutions in case $...
