宇宙学新质量引力与二维伽利略共形代数

Cosmological New Massive Gravity and Galilean Conformal Algebra in 2-dimensions

M. R. Setare, V. Kamali

摘要:

本文考虑$2-$维伽利略共形代数($GCA_2$)在宇宙学新质量引力边界上的实现.首先考虑收缩BTZ黑洞解。利用收缩的标度维数$Δ$和中心荷$C_1$得到了$GCA_2$的熵公式.该熵公式与BTZ黑洞的Bekenstein-Hawking熵的非相对论极限完全吻合。然后我们将研究扩展到CNMG的收缩翘曲$AdS_3$黑洞解。我们得到了用中心荷和有限温度表示的对偶$GCA_2$的熵$T_1, T_2$。该表达式再次与扭曲$AdS_3$黑洞的贝肯斯坦-霍金熵公式的非相对论极限相一致。

英文摘要:

In the present paper we consider the realization of $2-$dimensional Galilean conformal algebra ($GCA_2$) on the boundary of cosmological new massive gravity. At first we consider the contracted BTZ black hole solution. We obtain entropy formula for the $GCA_2$ in term of contracted scaling dimension $Δ$ and central charge $C_1$. This entropy formula exactly matches with the non-relativistic limit of Bekenstein-Hawking entropy of BTZ black hole. Then we extend our study to the contracted warped $AdS_3$ black hole solution of CNMG. We obtain the entropy of dual $GCA_2$ in terms of central charges and finite temperatures, $T_1, T_2$. Again this expression coincides with the non-relativistic limit of Bekenstein-Hawking entropy formula of warped $AdS_3$ black hole.
