彩虹黑洞热力学与广义不确定原理

Rainbow black hole thermodynamics and the generalized uncertainty principle

Rituparna Mandal, Sukanta Bhattacharyya, Sunandan Gangopadhyay

摘要:

在广义不确定原理的作用下,研究了彩虹激发的高维Schwarzschild黑洞的相变。首先,在修正色散关系和广义不确定原理的影响下,得到了彩虹黑洞的质量与Hawking温度的关系.然后从这个关系式计算热容,这表明有残余物。黑洞的熵接下来在$3+1$和$4+1$ -维中获得,并且发现仅在$3+1$ -维中具有对数校正。进一步研究了等温腔中黑洞的局域温度、自由能和稳定性。从自由能的分析中,我们发现在考虑广义不确定原理的情况下,在$3+1$和$4+1$ -维中存在两个Hawking-Page型相变.然而,在没有广义不确定原理的情况下,在大于四维的时空中只存在一种霍金-佩奇型相变。

英文摘要:

We study the phase transition of rainbow inspired higher dimensional Schwarzschild black hole incorporating the effects of the generalized uncertainty principle. First, we obtain the relation between the mass and Hawking temperature of the rainbow inspired black hole taking into account the effects of the modified dispersion relation and the generalized uncertainty principle. The heat capacity is then computed from this relation which reveals that there are remnants. The entropy of the black hole is next obtained in $3+1$ and $4+1$-dimensions and is found to have logarithmic corrections only in $3+1$-dimensions. We further investigate the local temperature, free energy and stability of the black hole in an isothermal cavity. From the analysis of the free energy, we find that there are two Hawking-Page type phase transitions in $3+1$ and $4+1$-dimensions if we take into account the generalized uncertainty principle. However, in the absence of the generalized uncertainty principle, only one Hawking-Page type phase transition exists in spacetime dimensions greater than four.
