该文运用统计力学方法研究了内表面位于施瓦西黑洞视界附近的具有普朗克长度的费米子壳层的热力学性质.根据费米子巨配分函数的定义式,通过对协变相空间体积的计算,得到了费米子的巨配分函数的具体表达式,由此在弯曲时空中发现了在非零温度下费米子会出现凝聚现象.通过分析Schwarzs-child黑洞视界附近费米子气体的熵发现,它表现出类似于Bekenstein-Hawking熵的面积依赖性.当把这些推向D+1 维球对称静态时空时,以上结论仍然成立.这些结果为黑洞热力学的研究提供了新的视角.
The Fermionic Shells in Spherically Symmetric Space-Time
The thermodynamic properties of fermionic shells with planck-length inner surfaces near from the Schwarzschild black hole horizon are studied by means of statistical mechanics.From the fermion giant partition function definition,the concrete expression of the giant partition function is obtained through the calculation of co-variant space volume.It is found that fermions condenses at non-zero temperatures in curved spacetime.By analyzing the entropy of fermionic gas near the Schwarzschild black hole event horizon,it exhibits an area dependence similar to entropy.Is is also true when applied to(D+1)-dimensional spherically symmetric static spacetime.These results provide a new perspective for the study of black hole thermodynamics.
