摘　　要：利用一种新的半经典的周期性的方法计算了三维Gdel黑洞视界面积和熵的量子修正谱.结果发现量子修正后的视界面积谱存在高阶的面积倒数的修正项,然而修正后的熵谱仍然是一个普适的常数,ΔS BH=2π.结论表明熵谱不仅不依赖于黑洞的基本参量,而且不依赖于高阶的量子修正,因而在量子引力理论中熵谱比视界面积谱更有意义.Quantum corrections to the area spectrum an the entropy spectrum of three dimensional G^del black hole are calculated by a new simple semi-classical scheme via periodicity, In the presence of higher -order quantum corrections, the area spectrum is found to be corrected by inverse area terms while the entropy spectrum is found to have a universa/form, ΔSBH = 2π. The results show that the entropy spec- trum is independent of not only the Godel black hole parameters but also the higher-order quantum cor- rections, which implies that the entropy spectrum is more natural than the area spectrum in quantum grav- ity theory.
