Existence and Stability of Spinning Embedded Vortices
I show the existence of a new type of vortex solution which is nonstatic but stationary and carries angular momentum. This spinning vortex can be embedded in models with trivial vacuum topology like a model with SU(2)global × U(1)local → U(1)global symmetry breaking. The stability properties of the embedded spinning vortex are also studied in detail and it is shown that stability improves drast...
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...
متن کاملFresnel Lens with Embedded Vortices
Vortices of different charges are embedded in a wavefront that has quadratic phase variation, and the intensity distribution near the focal plane is studied. This method may be useful in realizing complicated beam profiles. We have experimentally demonstrated the generation of vortex arrays having integer as well as fractional topological charges that produce different intensity profiles at the...
متن کاملStable vs Unstable Vortices in SQCD
We give a topological classification of stable and unconfined massive particles and strings (and some instantons) in worldvolume theories of M5-branes and their dimensional reductions, generalizing Witten’s classification of strings in SYM. In particular 4d N = 2 SQCD softly broken to N = 1 contains torsion (Douglas-Shenker) ZN strings and nontorsion (Hanany-Tong) Z-strings. Some of the former ...
متن کاملStable embedded solitons.
Stable embedded solitons are discovered in the generalized third-order nonlinear Schrödinger equation. When this equation can be reduced to a perturbed complex modified Korteweg-de Vries equation, we developed a soliton perturbation theory which shows that a continuous family of sech-shaped embedded solitons exist and are nonlinearly stable. These analytical results are confirmed by our numeric...
