Four-dimensional Lattice Gauge Theory with ribbon categories and the Crane–Yetter state sum
Lattice Gauge Theory in 4-dimensional Euclidean space-time is generalized to ribbon categories which replace the category of representations of the gauge group. This provides a framework in which the gauge group becomes a quantum group while space-time is still given by the ‘classical’ lattice. At the technical level, this construction generalizes the Spin Foam Model dual to Lattice Gauge Theor...
متن کاملFinite Temperature Sum Rules in Lattice Gauge Theory
We derive non-perturbative sum rules in SU(N) lattice gauge theory at finite temperature. They relate the susceptibilities of the trace anomaly and energy-momentum tensor to temperature derivatives of the thermodynamic potentials. Two of them have been derived previously in the continuum and one is new. In all cases, at finite latttice spacing there are important corrections to the continuum su...
متن کاملUnifying all classical spin models in a lattice gauge theory.
The partition function of all classical spin models, including all discrete standard statistical models and all Abelian discrete lattice gauge theories (LGTs), is expressed as a special instance of the partition function of the 4D Z2 LGT. This unifies all classical spin models with apparently very different features in a single complete model. This result is applied to establish a new method to...
متن کاملLattice Gauge Theory
Supercomputers have recently become a crucial tool for the quantum field the-orist. Applied to the formalism of lattice gauge theory, numerical simulations are providing fundamental quantitative information about the interactions of quarks, the fundamental constituents of those particles which experience nuclear interactions. Perhaps most strikingly, these simulations have provided convincing e...
متن کاملGauge Theory Invariants, and Surgery on Knots
Paul Kirk* ABSTRACT: Chern-Simons and spectral flow invariants of representations of 3-manifold groups are investigated in the context of Dehn surgery on knots. Various formulae and computational methods are explained, and examples are worked out. The guiding principle is that information about these invariants can be obtained entirely from the representation varieties of the manifolds, i.e. wi...
