Approximated seventh order calculation of vacuum wave function of 2+1 dimensional SU(2) lattice gauge theory
نویسندگان
چکیده
Using the coupled cluster expansion with the random phase approximation, we calculate the long wavelength vacuum wave function and the vacuum energy of 2+1 dimensional Hamiltonian SU(2) lattice gauge theory (LGT) up to the seventh order. The coefficients μ0 , μ2 of the vacuum wave function show good scaling behavior and convergence in high order calculations. PACS indices: 11.15.Ha, 12.38.Gc

Wave Functions for SU(2) Hamiltonian Lattice Gauge Theory
We study four dimensional SU(2) lattice gauge theory in the Hamiltonian formalism by Green’s Function Monte Carlo methods. A trial ground state wave function is introduced to improve the configuration sampling and we discuss the interplay between its complexity and the simulation systematic errors. As a case study, we compare the leading strong coupling approximation and an improved 4 parameter...
متن کاملSavvidy "ferromagnetic vacuum" in three-dimensional lattice gauge theory.
The vacuum effective potential of three-dimensional SU(2) lattice gauge theory in an applied color-magnetic field is computed over a wide range of field strengths. The background field is induced by an external current, as in continuum field theory. Scaling and finite volume effects are analyzed systematically. The first evidence from lattice simulations is obtained of the existence of a nontri...

The vacuum expectation value of the Wilson loop functional in pure Yang-Mills theory on an arbitrary two-dimensional orientable manifold is studied. We consider the calculation of this quantity for the abelian theory in the continuum case and for the arbitrary gauge group and arbitrary lattice action in the lattice case. A classification of topological sectors of the theory and the related clas...
متن کاملConfinement and scaling of the vortex vacuum of SU ( 2 ) lattice gauge theory ∗
The magnetic vortices which arise in SU(2) lattice gauge theory in center projection are visualized for a given time slice. We establish that the number of vortices piercing a given 2-dimensional sheet is a renormalization group invariant and therefore physical quantity. We find that roughly 2 vortices pierce an area of 1 fm. ∗ Supported in part by DFG under contract Re 856/1–3.
متن کاملساختار فاز میدانهای پیمانهای شبکهای دو بعدی U(N) با کنش مختلط
We study the phase structure of two dimensional pure lattice gauge theory with a Chern term. The symmetry groups are non-Abelian, finite and disconnected sub-groups of SU(3). Since the action is imaginary it introduces a rich phase structure compared to the originally trivial two dimensional pure gauge theory. The Z3 group is the center of these groups and the result shows that if we use one ...
