Einstein-Gauss-Bonnet体中的畴壁

Domain-Walls in Einstein-Gauss-Bonnet Bulk

S. Habib Mazharimousavi, M. Halilsoy

摘要:

研究了d+1维Einstein-Gauss-Bonnet(EGB)体中d维畴壁的动力学行为.导出了高斯-博内(GB)项在壁面上诱导的有效势的精确表达式。在没有GB项的情况下,我们恢复了熟悉的引力势和反谐振子势。包含GB校正引起的最小反弹半径的Friedmann-Robertson-Walker(FRW)宇宙膨胀的DW上的负压。

英文摘要:

We investigate the dynamics of a d-dimensional domain wall (DW) in a d+1-dimensional Einstein-Gauss-Bonnet (EGB) bulk. Exact effective potential induced by the Gauss-Bonnet (GB) term on the wall is derived. In the absence of the GB term we recover the familiar gravitational and anti-harmonic oscillator potentials. Inclusion of the GB correction gives rise to a minimum radius of bounce for the Friedmann-Robertson-Walker (FRW) universe expanding with a negative pressure on the DW.
