用超越半经典近似的隧道方法计算了各种黑洞和FRW宇宙模型的修正Hawking温度和熵。我们研究了它们的导数,并证明了修正温度中的量H是唯一自由参数λ的显式函数(如果我们应用变量的变化λ = λ SBH)。我们的分析改进了以前的计算,并指出,领导阶对数修正熵是一个自然的结果,修正的温度和热力学第一定律。此外,我们应用隧道方法超越半经典近似的中性黑环。在此基础上,我们证明了中性黑环的熵也具有对数超前阶修正。
The tunneling approach beyond the semiclassical approximation has been used to calculate the corrected Hawking temperature and entropy for various black holes and FRW universe model. We examine their derivations, and show that the quantity H in the corrected temperature is the explicit function of the only free parameter ℱ (if we apply the change of variables ℱ = ℏSBH). Our analysis improves previous calculations, and indicates that the leading-order logarithmic correction to entropy is a natural result of the corrected temperature and the first law of thermodynamics. Additionally, we apply the tunneling approach beyond semiclassical approximation to neutral black rings. Based on the analysis, we show that the entropy of neutral black rings also has a logarithmic leading-order correction.
