对牛顿万有引力定律的修正--应用于杂化Bloch膜
Corrections to Newton's law of gravitation - application to hybrid Bloch brane
摘要：
在这项工作中，我们提出的计算修正牛顿引力定律由于卡鲁扎-克莱因引力子在五维扭曲厚膜世界的情况下。在这里，我们考虑最近提出的模型，即混合Bloch膜。该模型将两个标量场耦合到重力场，并由畴壁状缺陷产生。此外，我们还考虑了另外两种模型，即所谓的非对称杂化膜和紧膜。事实上，这些模型是从phi 4和sine-Gordon拓扑缺陷的变形中获得的。然后，我们构造了这种缺陷上的膜，并计算了牛顿引力定律中相应的修正。为了获得质量谱及其相应的本征函数，这是计算牛顿势修正的基本量，我们开发了一个合适的数值技术。
英文摘要：
We present in this work, the calculations of corrections in the Newton's law of gravitation due to Kaluza-Klein gravitons in five-dimensional warped thick braneworld scenarios. We consider here a recently proposed model, namely, the hybrid Bloch brane. This model couples two scalar fields to gravity and is engendered from a domain wall-like defect. Also, two other models the so-called asymmetric hybrid brane and compact brane are considered. As a matter of fact, these models are obtained from deformations of the phi4 and sine-Gordon topological defects. Then, we constructed the branes upon such defects, and the corresponding corrections in Newton's law of gravitation are computed. In order to attain the mass spectrum and its corresponding eigenfunctions which are the essential quantities for computing the correction to the Newtonian potential, we develop a suitable numerical technique.
