三维Lifshitz黑洞的膨胀引力近似

Dilaton gravity approach to three dimensional Lifshitz black hole

Yun Soo Myung, Yong-Wan Kim, Young-Jai Park

摘要:

z=3的Lifshitz黑洞是新的大质量引力在三维中的精确黑洞解。为了更好地理解这个黑洞,我们利用圆对称对二维引力场进行了降维。考虑到线性玻色子,我们发现在二维中存在相同的Lifshitz黑洞。这意味着z=3的Lifshitz黑洞的所有热力学量都可以从其对应的二维黑洞得到。结果,我们得到了温度,质量,热容,Bekesnstein-Hawking熵和自由能。

英文摘要:

The z=3 Lifshitz black hole is an exact black hole solution to the new massive gravity in three dimensions. In order to understand this black hole clearly, we perform a dimensional reduction to two dimensional dilaton gravity by utilizing the circular symmetry. Considering the linear dilaton, we find the same Lifshitz black hole in two dimensions. This implies that all thermodynamic quantities of the z=3 Lifshitz black hole could be obtained from its corresponding black hole in two dimensions. As a result, we derive the temperature, mass, heat capacity, Bekesnstein-Hawking entropy, and free energy.
