论文摘要
高维时段中的爱因斯坦 - 加斯 - 邦网重力令人着迷。在这里，研究了五维爱因斯坦 - 加斯 - 尼斯重力重力中散装标量场产生的厚麸皮的性质。借助超电球方法，我们获得了一系列多晶管brane解决方案。我们还分析了在张量扰动下的棕褐色系统的线性稳定性，并证明它们是稳定的。无质量的重力显示在勃雷附近，因此可以回收四维牛顿电位。通过比较在不同超电势下的这些厚麸皮的特性，我们可以通过某种特定的超电势选择，高斯 - 骨网术语可以确定标量场是多旋转或单个扭结。
Einstein-Gauss-Bonnet gravity in high dimensional spacetime is intriguing. Here, the properties of thick branes generated by a bulk scalar field in the five-dimensional Einstein-Gauss-Bonnet gravity were studied. With the help of the superpotential method, we obtain a series of multi-kink brane solutions. We also analyze the linear stability of the brane system under tensor perturbations and prove that they are stable. The massless graviton is shown to be localized near the brane and hence the four-dimensional Newtonian potential can be recovered. By comparing the properties of these thick branes under different superpotentials we find with some specific choice of superpotential the Gauss-Bonnet term can determine the scalar field are multi-kink or single kink.
