扭结和壁的小变形

Small deformations of kinks and walls

J. R. Morris

摘要:

采用Rayleigh-Schrodinger型微扰方法研究了描述一维畴结和三维畴壁的标量场模型中的弱自相互作用标量位微扰。未扰动缺陷的解被微扰势修正。一个例子是通过添加一个立方势熟悉的四次扭结势和解决的扭结解决方案的一阶修正,使用“板近似”。其结果是一个不对称的标量势与不同的外观,非简并,真空值和随后形成的真空泡。

英文摘要:

A Rayleigh-Schrodinger type of perturbation scheme is employed to study weak self-interacting scalar potential perturbations occurring in scalar field models describing 1D domain kinks and 3D domain walls. The solutions for the unperturbed defects are modified by the perturbing potentials. An illustration is provided by adding a cubic potential to the familiar quartic kink potential and solving for the first order correction to the kink solution, using a "slab approximation". A result is the appearance of an asymmetric scalar potential with different, nondegenerate, vacuum values and the subsequent formation of vacuum bubbles.
