最近，Lu和Pope在《物理学》中提出了临界引力。Rev. Lett. 106, 181302(2011)]。本文构造了临界重力条件下含物质的解析膜解。研究了Gibbons- Hawking表面项和结条件，得到了薄膜解和厚膜解。所有这些膜都嵌入在五维反德西特时空中。我们的解对标量扰动是稳定的，并且标量扰动的零模不能在膜上定域。
Recently, Lu and Pope proposed critical gravities in [Phys. Rev. Lett. 106, 181302 (2011)]. In this paper we construct analytic brane solutions in critical gravity with matter. The Gibbons- Hawking surface term and junction condition are investigated, and the thin and thick brane solutions are obtained. All these branes are embedded in five- dimensional anti-de Sitter spacetimes. Our solutions are stable against scalar perturbations, and the zero modes of scalar perturbations cannot be localized on the branes.
