对数熵的发现对红外变形的Hoenava-Lifshitz（IRDHL）引力产生了重要影响，在IRDHL引力中引入了三几何的Ricci标量项μ4 R，改进了原有的红外（IR）性质.本文利用新近提出的新的哈密顿-雅可比方法（NHJM）重新计算了IRDHL中的Hawking辐射。特别是，一个彻底的分析被认为是在渐近平坦的Kehagias-Sfetsos和渐近非平坦的公园模型在IRDHL。我们发现NHJM在技术方面提供了简化。在这种新的哈密顿-雅可比（HJ）观点下，通过对霍金辐射自引力的物理解释，给出了熵表达式的修正。
The apparent discovery of logarithmic entropies has a significant impact on IR deformed Hořava–Lifshitz (IRDHL) gravity in which the original infrared (IR) property is improved by introducing three-geometry's Ricci scalar term "μ4 R" in action. Here, we reevaluate the Hawking radiation in IRDHL by using recent new Hamilton–Jacobi method (NHJM). In particular, a thorough analysis is considered both in asymptotically flat Kehagias–Sfetsos and asymptotically non-flat Park models in IRDHL. We find the NHJM offers simplifications on the technical side. The modification in the entropy expression is given by the physical interpretation of self-gravitation of the Hawking radiation in this new Hamilton–Jacobi (HJ) perspectives.
