约化Born-Infeld- $f(T)$理论中的畴壁膜

Domain wall brane in a reduced Born-Infeld-$f(T)$ theory

Ke Yang, Wen-Di Guo, Zi-Chao Lin, Yu-Xiao Liu

摘要:

Born-Infeld $f(T)$理论是从Weitzenböck时空中的Born-Infeld行列式引力约化而来的。我们研究了膜世界的情况下,在这个理论,并获得一个解析的域壁解决方案,利用一阶形式。该模型对线性张量扰动是稳定的。结果表明,无质量引力子在膜上是局域的,而连续的有质量引力子是非局域的,并且随着${1}/{(k r)^{3}}$的行为对牛顿势产生微小的修正.四维遥平行引力被恢复为膜上的有效红外理论。作为物理应用,我们考虑了自旋为1/2的狄拉克费米子在该模型中的(准)局域化性质。

英文摘要:

The Born-Infeld $f(T)$ theory is reduced from the Born-Infeld determinantal gravity in Weitzenböck spacetime. We investigate a braneworld scenario in this theory and obtain an analytic domain wall solution by utilizing the first-order formalism. The model is stable against the linear tensor perturbation. It is shown that the massless graviton is localized on the brane, but the continuous massive gravitons are non-localized and will generate a tiny correction with the behavior of ${1}/{(k r)^{3}}$ to the Newtonian potential. The four-dimensional teleparallel gravity is recovered as an effective infrared theory on the brane. As a physical application, we consider the (quasi-)localization property of spin-1/2 Dirac fermion in this model.
