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.
