最近,在爱因斯坦引力理论中,Majhi和Padmanabhan提出了一种基于Virasoro代数和中心电荷的方法来获得贝肯斯坦-霍金熵的直接而透明的方法。在这项工作中,我们将他们的方法推广到具有高曲率修正的修正重力,并表明他们的方法可以成功地导致高曲率重力中相应的Wald熵。结果表明,该方法在物理上是通用的。
Recently, in the Einstein gravity, Majhi and Padmanabhan proposed a straightforward and transparent way of obtaining the Bekenstein-Hawking entropy by using an approach based on the Virasoro algebra and central charge. In this work, we generalize their approach to the modified gravity with higher-curvature corrections and show that their approach can successfully lead to the corresponding Wald entropy in the higher-curvature gravity. Our result shows that the approach is physically general.
