论文摘要
在这项工作中,我们研究了从AD到DS渐近几何形状的引力相变的存在,通过添加Maxwell Oneform Field($a_μ$)和Kalb-Ramond两种形式场($ b_ {μNν} $),作为Impurity empurity repentutions。相变是通过用溶液的不同分支描述的球形薄壳的气泡成核进行的,这些溶液的不同分支在内部携带了一个DS黑洞,而外部的渐近热广告状态则进行。我们分析了自由能和温度的相图,以证明大规范合奏中的相变存在(固定电势)。具有单形式和两种电荷的相变是可能的,其中临界温度低于中性情况。将结果与现有文献进行比较,更重要的是,我们的分析表明,相变的临界温度和高斯 - 骨网耦合$λ$通过添加更多类型的指控而减少。
In this work, we study the possible existence of gravitational phase transition from AdS to dS asymptotic geometries in Einstein-Gauss-Bonnet gravity by adding the Maxwell one-form field ($A_μ$) and the Kalb-Ramond two-form field ($B_{μν}$) as impurity substitutions. The phase transitions proceed via the bubble nucleation of spherical thin-shells described by different branches of the solutions which host a dS black hole in the interior and asymptotic thermal AdS state in the exterior. We analyze the phase diagrams of the free energy and temperature to demonstrate the existence of the phase transitions in the grand canonical ensemble (fixed electrical potential). The phase transitions of having the one-form and two-form charges are possible in which the critical temperature is lower than that of the neutral case. Comparing results with existing literature, more importantly, our analyses show that the critical temperature and the Gauss-Bonnet coupling $λ$ of the phase transitions get decreased by adding more types of the charges.
