论文摘要
在这项工作中,研究了Rastall重力的厚麸皮。构建了三种类型的最大对称厚的浓密的棕褐色模型,并分析了线性张量的扰动。在扁平模型中,对于非呈现的rastall参数,扰动的张量模式是不稳定的或不稳定的。在De Sitter Brane模型中,只有张量模式的基态位置。在抗DE保姆Brane模型中,结合张量状态的数量是无穷大的。对于De Sitter和Anti-DE保姆Brane模型,都可以获得Rastall参数的稳定性条件。
In this work, thick branes in Rastall gravity are investigated. Three types of maximally symmetric thick brane models are constructed and the linear tensor perturbation is analyzed. In the flat brane model, the tensor modes of the perturbation are either unstable or nonlocalizable for a nonvanishing Rastall parameter. In the de Sitter brane model, only the ground state of the tensor mode is localized. In the anti-de Sitter brane model, the number of the bound tensor states is infinity. For both the de Sitter and anti-de Sitter brane models, the condition of stability for the Rastall parameter is obtained.
