Vortices in SU(2) lattice gauge theory

چکیده
We investigate some properties of thick vortices and thick monopoles in the SU(2) lattice gauge theory by inserting operators which create these excitations. Some quantities associated with the dynamical behaviour of thick vortices and thick monopoles are studied. We measure the derivative of the free energy of the vortex with respect to the coupling and we find that it falls exponentially with the cross sectional area of the vortex size. We also study the monopole-monopole potential energy for thick and thin monopoles. Our results suggest that vortices and monopoles of increasing thickness will play an important role in the large β limit. PACS numbers:12.38Gc,11.15Ha,05.70Fh,02.70g

A phase transition due to thick vortices in SU(2) lattice gauge theory
SU(2) lattice gauge theory is studied after eliminating thin monopoles and the smallest thick monopoles. Kinematically this constraint allows thick vortex loops which produce long range Z(2) fluctuations. The thick vortex loops are identified in a three dimensional simulation. A condensate of thick vortices persists even after the thin vortices have all disappeared. They decouple at a slightly ...

We study monopoles and vortices in SU (2) lattice gauge theory on a 24 4 lattice at β = 2.50. We find a value of fundamental string tension from monopoles in the maximum Abelian gauge consistent with the full SU (2) value. Using direct and indirect center gauges, we find fundamental string tension values from P-vortices which are larger than the full SU (2) result. After a single cooling sweep,...
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 کاملInteraction of confining vortices in SU ( 2 ) lattice gauge theory ∗
Center projection of SU(2) lattice gauge theory allows to isolate magnetic vortices as confining configurations. The vortex density scales according to the renormalization group, implying that the vortices are physical objects rather than lattice artifacts. Here, the binary correlations between points at which vortices pierce a given plane are investigated. We find an attractive interaction bet...
متن کاملVortex solutions in SU(N ) adjoint Higgs theories
A relationship between vortex solutions in SU(N) gauge theories with two or more adjoint representation Higgs bosons and thick vortices of Center Vortex Theory is shown to exist. There is a similar relationship between monopole solutions of SU(N) gauge theories with a single adjoint representation Higgs boson and monopoles in Abelian Projection. New vortex solutions, relevant in central gauge f...
