Borel resummation of secular divergences in stochastic inflation

M Honda, R Jinno, L Pinol, K Tokeshi - Journal of High Energy Physics, 2023 - Springer
A bstract We make use of Borel resummation to extract the exact time dependence from the
divergent series found in the context of stochastic inflation. Correlation functions of self …

mathematics. While leading instanton effects can be calculated simply as an exponent of the …

Recursive generation of the semiclassical expansion in arbitrary dimension

C Pazarbaşı - Physical Review D, 2021 - APS
We present a recursive procedure, which is based on the small time expansion of the
propagator, in order to generate a semiclassical expansion of the quantum action for a …

Pair Production in Real Proper Time and Unitarity Without Borel Ambiguity
