采用由广义测不准关系得到的新的态密度方程,研究了具有柱对称时空背景下黑柱的 熵.利用新的态密度方程后,不通过截断可以消除brick-wall模型中无法克服的发散项,并且 同样可得到黑柱的熵与视界面积成正比的结论.计算结果表明,黑柱熵是视界面上量子态的 熵,是一种量子效应,是黑洞的内禀性质.在计算中我们直接应用量子统计的方法,求柱黑洞 背景下玻色场与费米场的配分函数,避开了求解各种粒子波动方程的困难,为研究各种时空黑 洞熵提供了一条简捷的新途经. 相似文献

Single-particle resonant states in spherical nuclei are studied by the real stabilization method in coordinate space within the framework of self-consistent relativistic mean field theory. Taking 122Zr as an example, the resonant parameters, including the energies and widths are extracted by fitting energy and phase shift. Good agreement with the previous calculations has been found. The details of single-particle resonant states are analysed. 相似文献
