We propose a simple but novel cosmological scenario where both the Planck mass and the dark energy scale emerge from the same super-Hubble quantum fluctuations of a non-minimally coupled ultra-light scalar field during primordial inflation. The current cosmic and solar-system observations constrain the non-minimal coupling to be small.

Friction in Stochastic Inflation
Adding a constant drift to time-reversed stochastic inflation in a flat potential yields an exact curvature distribution with exponential tails; forward and reverse delta-N formalisms differ by a factor of two in the ...

Stochastic inflation with an extremely large number of $e$-folds
A shallow local minimum added to a hilltop inflation potential can make the typical number of e-folds as large as 10^(10^10), enough for light scalars to reach Bunch-Davies equilibrium.
