Vortices ∗
I discuss in these lectures vortex-like classical solutions to the equations of motion of gauge theories with spontaneous symmetry breaking. Starting from the Nielsen-Olesen ansatz for the Abelian Higgs model, extensions to the case in which gauge dynamics is governed by Yang-Mills and Chern-Simons actions are presented. The case of semilocal vortices and also the coupling to axions is analyzed...
متن کاملDisturbing Vortices
Inviscid spatially compact vortices (such as the Rankine vortex) have discrete Kelvin modes. For these modes, the critical radius, at which the rotation frequency of the wave matches the angular velocity of the fluid, lies outside the vortex core. When such a vortex is not perfectly compact, but has a weak vorticity distribution beyond the core, these Kelvin disturbances are singular at the cri...
متن کاملVortices, Confinement
We review lattice evidence for the vortex mechanism of quark confinement and study the influence of charged matter fields on the vortex distribution. 1 Review of the vortex mechanism of quark confinement In the early days of QCD some people argued that quarks are confined due to the non-abelian nature of gauge-fields leading to attraction between flux-lines. But the abelian U(1) lattice gauge t...
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 کاملEmbedded Vortices
We present a discussion of embedded vortices in general Yang-Mills theories. The origin of a family structure of solutions is shown to be group theoretic in nature and a procedure for its determination is developed. Vortex stability can be quantified into three types: Abelian topological stability, non-Abelian topological stability, and dynamical stability; we relate these to the family structu...
