论文摘要
通常,基于欧几里得功能方法的长臂猿温度表明,束戴维斯真空中的灵长种空间是全球热的。在确切的可溶性半经典jackiw-teitelboim模型中,我们通过考虑几何形状的量子背部反应来研究DE Sitter空间的热性能。发现束戴式真空中的De Sitter空间的适当温度被发现消失。如果某种量子状态破坏了de de Sitter对称性,则可以热退出安慰剂空间。但是,在这种情况下,无法避免Dilaton的奇异性。因此,在Jackiw-teitelboim模型中,束戴式真空中的De Sitter空间的适当温度被证明为零,并且发现Bunch-Davies真空吸尘器是唯一没有任何裸露奇异性的物理真空。
In general, the Gibbons-Hawking temperature based on the Euclidean functional approach shows that de Sitter space in the Bunch-Davies vacuum is globally thermal. In the exactly soluble semiclassical Jackiw-Teitelboim model, we investigate thermal property of de Sitter space by taking into account the quantum back reaction of the geometry. The proper temperature of de Sitter space in the Bunch-Davies vacuum is found to vanish. In case of a certain quantum state breaking the de Sitter symmetry, de Sitter space can be made thermally exited; however, in this case the dilaton singularity cannot be avoided. Consequently, in the Jackiw-Teitelboim model the proper temperature of de Sitter space in the Bunch-Davies vacuum turns out to be zero and the Bunch-Davies vacuum is found to be the only physical vacuum without any naked singularities.
