Topological charge of Center Vortices
Center vortices provide an appealing picture of confinement [1]. When center vortices are removed from the Yang-Mills ensemble, the string tension [2] and the quark condensate [3] are lost. Therefore one should expect that center vortices can also explain spontaneous breaking of chiral symmetry. The mechanism of spontaneous breaking of chiral symmetry seems to be tied to the topological propert...
متن کاملCenter vortices, nexuses, and fractional topological charge
It has been remarked in several previous works that the combination of center vortices and nexuses (a nexus is a monopole-like soliton whose world line mediates certain allowed changes of field strengths on vortex surfaces) carry topological charge quantized in units of 1/N for gauge group SU(N). These fractional charges arise from the interpretation of the standard topological charge ∫ GG̃ as a...
متن کاملTopological charge algebra of optical vortices in nonlinear interactions.
We investigate the transfer of orbital angular momentum among multiple beams involved in a coherent Raman interaction. We use a liquid crystal light modulator to shape pump and Stokes beams into optical vortices with various integer values of topological charge, and cross them in a Raman-active crystal to produce multiple Stokes and anti-Stokes sidebands. We measure the resultant vortex charges...
متن کاملCenter Vortices
We review recent progress in understanding the center-vortex picture of con nement for SU(N). A notable development is the spectacular con rmation on the lattice of center-vortex predictions for topological con nement and the area law in the fundamental-representation Wilson loop. Recent theoretical progress includes: large-N scaling, the heavy-quark potential for SU(3) baryons, the breakable \...
متن کاملTopology of Center Vortices
The topology of center vortices is studied. For this purpose it is sufficient to consider mathematically idealised vortices, defined in a gauge invariant way as closed (infinitely thin) flux surfaces (in D=4 dimensions) which contribute the nth power of a non-trivial center element to Wilson loops when they are n-foldly linked to the latter. In ordinary 3-space generic center vortices represent...
