Loop Action for Lattice U(1) Gauge Theory
It is showed that the very recently introduced Lagrangian loop formulation of the lattice Maxwell theory is equivalent to the Villain form in 2+1 dimensions. A transparent description of the classical loop action is given in pure geometrical terms for the 2 + 1 and 3 + 1 dimensional cases. The loop formalism was introduced some time ago as a general analytical Hamiltonian approach based on the ...
متن کاملMonopole Loop Suppression and Loss of Confinement in Restricted Action SU(2) Lattice Gauge Theory
The effect of restricting the plaquette (1× 1 Wilson loop) to be greater than a certain cutoff is studied. The action considered is the standard Wilson action with the addition of the plaquette restriction, which does not affect the continuum limit. A deconfining phase transition occurs as the cutoff is raised, even in the strong coupling limit. Abelian-projected monopoles in the maximal abelia...
متن کاملThe Lagrangian Loop Representation of Lattice U(1) Gauge Theory
It is showed how the Hamiltonian lattice loop representation can be cast straightforwardly in the Lagrangian formalism. The procedure is general and here we present the simplest case: pure compact QED. This connection has been shaded by the non canonical character of the algebra of the fundamental loop operators. The loops represent tubes of electric flux and can be considered the dual objects ...
متن کاملNew Results from Mixed-action Lattice Gauge Theory
Lattice gauge theory involves a particular choice of discretisation of the gauge action, notably in the representation of the gauge group. Physical results should be independent of that choice (an example of universality). We use a combination of two different representations: in our case, only one of these is irreducible. We extend and attempt to clarify recent results which showed possible pr...
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...
