In this study, we consider the semi-classical expansion of the Bunch-Davies wavefunction with future boundary condition for a real scalar field conformally coupled to a classical de Sitter background. The wave function takes the form of the generating functional of a Euclidean conformal field theory in the future boundary limit, for which we calculate anomalous dimensions of double trace deformations at one loop order. Additionally, we find analytic expressions for some subleading twist operators and present an algorithm for obtaining expressions for general twist.
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 Poincare 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.
