论文摘要
在这项工作中，我们介绍了在新型的4D Einstein-Gauss-Bonnet（EGB）重力的背景下，ADS与DS渐近几何形状之间的热相转变可能存在。相转换通过Thermalon（气泡薄壳的欧几里得扇区）进行进行，在DS时空内部内部有一个黑洞，外部的热广告时空在没有任何物质场的情况下进行。根据我们的分析，我们发现使用新型4D EGB重力的重力相变为4D EGB耦合的所有存在。与5维EGB重力相反，相变的存在需要4D EGB耦合与特定临界值的狭窄范围，而5维扇区的范围更大，其对Thermalon的存在的耦合范围更大，并且还存在相位过渡的临界值的临界值。
In this work, we present the possible existence of thermal phase transition between AdS to dS asymptotic geometries in vacuum in the context of novel 4D Einstein-Gauss-Bonnet (EGB) gravity. The phase transition proceeds through the thermalon (the Euclidean sector of the bubble thin-shell) formation having a black hole inside the interior of dS spacetime and a thermal AdS spacetime in the exterior without introducing any matter field. According to our analysis, we find that the gravitational phase transitions using novel 4D EGB gravity always take place for all existences of the 4D EGB coupling. In contrast to 5-dimensional EGB gravity, the existence of phase transition requires a narrow range of the 4D EGB coupling with particular critical values, while the 5-dimension sector has a wider range of its coupling for the existences of the thermalon and there also exist critical values for the emergence of the phase transition.
