Time-reversed stochastic inflation in tilted potentials

In a recent publication, Baptiste and Christophe have extended the time-reversed approach of stochastic inflation to the semi-infinite tilted potentials. For large positive tilts, the curvature fluctuations show some classical-like behaviour, their probability distribution transiting from exponential to Gaussian tails. For negative tilts, eternal inflation takes place. Yet, the time-reversed approach remains regular and produces finite results typical of quantum tunnelling.
