论文摘要
我们考虑束戴维斯波函数的半古典膨胀，并在真实标量场的位置空间中具有未来的边界条件，并在扩展的Poincaré贴片中与四分之一的自我互动中的经典de Sitter背景结合使用。在未来的边界限制中，波函数采用欧几里得形式的形式的欧几里得共形场理论的生成功能，我们使用从欧几里得抗De Sitter空间中获得的结果来计算一个双重痕量变形的异常尺寸。我们发现某些转向扭曲操作员和算法的分析表达式以获得一般扭曲的表达式。
We consider the semi-classical expansion of the Bunch-Davies wavefunction with future boundary condition in position space for a real scalar field, conformally coupled to a classical de Sitter background in the expanding Poincaré patch with quartic selfinteraction. In the future boundary limit the wave function takes the form of the generating functional of a Euclidean conformal field theory for which we calculate the anomalous dimensions of the double trace deformations at one loop order using results obtained from Euclidean Anti de Sitter space. We find analytic expressions for some subleading twist operators and an algorithm to obtain expressions for general twist.
