Scalar field stochastic dynamics in de Sitter spacetime from exact solutions of quantum deficient oscillators
Yuta Nasuda, Koki Tokeshi, Yuki Watanabe
The stochastic dynamics of a scalar field in de Sitter spacetime can be regarded as a non-perturbative diffusion process, to which exact distribution and correlation functions are…

Borel resummation of secular divergences in stochastic inflation
Masazumi Honda, Ryusuke Jinno, Lucas Pinol +1
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-interact…
