Peristaltic modes of a single vortex in the Abelian Higgs model
Abstract
Using the Abelian Higgs model, we study the radial excitations of single vortex and their propagation modes along the vortex line. We call such beyondstringy modes peristaltic modes of single vortex. With the profile of the static vortex, we derive the vortexinduced potential, i.e., singleparticle potential for the Higgs and the photon field fluctuations around the static vortex, and investigate the coherently propagating fluctuations which correspond to the vibration of the vortex. We derive, analyze, and numerically solve the field equations of the Higgs and the photon field fluctuations around the static vortex with various GinzburgLandau parameter {kappa} and topological charge n. Around the Bogomol'nyiPrasadSommerfield value or critical coupling {kappa}{sup 2}=1/2, there appears a significant correlation between the Higgs and the photon field fluctuations mediated by the static vortex. As a result, for {kappa}{sup 2}=1/2, we find the characteristic newtype discrete pole of the peristaltic mode corresponding to the quasibound state of coherently fluctuating fields and the static vortex. We investigate its excitation energy, correlation energy of coherent fluctuations, spatial distributions, and the resulting magnetic flux behavior in detail. Our investigation covers not only usual typeII vortices with n=1 but also typeI and typeII vortices with n setmembership sign Zmore »

Treating the flux of the magnetic field penetrating the vortex as a dynamical variable, we consider the question of the stability of the quantum state of the vortex against the decay to the excitations which are present in the Abelian Higgs model. Specifically, the partial widths of the decay to a pair of the scalar field excitations possessing the Bogolyubov spectrum and to such a pair plus the quantum of the electromagnetic field with the finite radius of propagation implied by the finite London penetration depth are evaluated.

Radiation from an excited vortex in the Abelian Higgs model
An excited vortex in the Abelian Higgs model is investigated with the help of a polynomial approximation. The excitation consists of the longitudinal component of a vector field trapped by the vortex. The energy and profile of the excitation as well as its back reaction on the vortex are found in the case of small {kappa}. It turns out that the width of the excited vortex oscillates in time. Moreover, the vector field has a radiative long range component. Also, an upper bound on the amplitude of the excitation is found. {copyright} {ital 1996 The American Physical Society.} 
Classical vortex solution of the Abelian Higgs model. [form factors, one and Nquantaofflux solutions]
An exact vortex solution for the Abelian Higgs model is found when a particular relation between the coupling constants is satisfied. For this case (in which the masses of the scalar and vector bosons are the same), we decouple the classical field equations and solve them. We obtain powerseries expansions and asymptotic expressions for the solution. The values of the fields are explicitly calculated for a onequantumofflux solution, and bounds are established for the nquanta case. Finally, we discuss the field form factors. (AIP) 
Compact Q=2 Abelian Higgs model in the London limit: Vortexmonopole chains and the photon propagator
The confining and topological properties of the compact Abelian Higgs model with doublycharged Higgs field in three spacetime dimensions are studied. We consider the London limit of the model. We show that the monopoles are forming chainlike structures (kept together by AbrikosovNielsenOlesen vortices), the presence of which is essential for getting simultaneously permanent confinement of singlycharged particles and breaking of the string spanned between doublycharged particles. In the confinement phase, the chains are forming percolating clusters, while in the deconfinement (Higgs) phase, the chains are of finite size. The described picture is in close analogy with the synthesis of themore » 
Oneloop corrections to the string tension of the vortex in the Abelian Higgs model
We present an exact numerical computation of the oneloop correction of the string tension for the NielsenOlesen vortex in the Abelian Higgs model. The computation proceeds via the computation of the Euclidean Green's function for the gauge, Higgs, and FaddeevPopov fields using mode functions, and taking the appropriate trace. Renormalization is an essential part of this computation. It is done by removing leading order contributions from the numerical results so as to make these finite, and to add the divergent parts back, after suitable regularization and renormalization. We encounter and solve some problems which are specific to gauge theories andmore »
