In this paper, we study the thermodynamic geometry for the charged Ad S black hole surrounded by quintessence. Three different kinds of the geometries are constructed, and the corresponding curvatures are obtained. It is found that there are different divergence behaviors of these curvatures, which is general thought to closely link to the phase transition of the black hole. 相似文献

利用拉格朗日量求解力学问题是一种很有用的方法.本文将借助于拉格朗日量求解黑洞时空背景下自由光子的运动,在求得光子的四速度之后,借助于机械能守恒定律,考察具有不同能量的光子在黑洞背景下所允许的运动范围.随后根据力学中运动学反问题,最终得到光子的运动轨迹. 相似文献

We investigate the area and entropy spectra of D-dimensional large Schwarzschild black holes. By utilizing the new physical interpretation of quasinormal mode frequency we find that a large Schwarzschild-AdS black hole has an equally spaced area spectrum and an equidistant entropy spectrum; both are dependent on the spacetime dimension. 相似文献
