标题： Backreaction of excitations on a vortex

摘要： 涡旋的激发通常是在线性近似下考虑的，忽略其对涡旋的反作用。 在本文中，我们在阿贝尔-希格斯模型中研究了Proca型激发对直线涡旋的反作用。 我们提出了激发涡旋场的精确Ansatz（假设）。 从初始的六个非线性场方程组中，我们得到了（在弱激发极限下）两个用于反作用修正的线性波动方程。 我们找到了平面波和波包型激发情况下的近似解。 我们发现激发的涡旋会辐射矢量场，并且Higgs场具有非常宽的振荡分量。 显示英文摘要

摘要： Excitations of a vortex are usually considered in a linear approximation neglecting their backreaction on the vortex. In the present paper we investigate backreaction of Proca type excitations on a straightlinear vortex in the Abelian Higgs model. We propose exact Ansatz for fields of the excited vortex. From initial set of six nonlinear field equations we obtain (in a limit of weak excitations) two linear wave equations for the backreaction corrections. Their approximate solutions are found in the cases of plane wave and wave packet type excitations. We find that the excited vortex radiates vector field and that the Higgs field has a very broad oscillating component.
