标量场模型中的类块结构

Lump-like Structures in Scalar-field Models

A. T. Avelar, D. Bazeia, W. B. Cardoso, L. Losano

摘要:

在这项工作中,我们研究了由一个单一的实标量场描述的模型中的块状解决方案的存在。我们利用最近用于描述明确的解析解的程序,我们研究了几种不同的模型,显示了如何参数可以用来控制的具体功能的块状结构。所提出的模型对q球的构造、在单额外维膜世界模型上诱导非拓扑轮廓的快子激发和引力结构、映射光纤中的孤子以及描述玻色-爱因斯坦凝聚体中的集体激发都有直接的意义。

英文摘要:

In this work we investigate the presence of lump-like solutions in models described by a single real scalar field. We take advantage of a procedure recently used to describe explicit analytical solutions and we study several distinct models, showing how the parameters can be used to control the specific features of the lump-like structures. The proposed models are of direct interest to the construction of q-balls, to induce tachyonic excitations and gravitating structures of nontopological profile on braneworld models with a single extra dimension, to map solitons in optical fibers, and to describe collective excitations in Bose-Einstein condensates.
