  The ultra-slow-roll (USR) inflation represents a class of single-field models
with sharp deceleration of the rolling dynamics on small scales, leading to a
significantly enhanced power spectrum of the curvature perturbations and
primordial black hole (PBH) formation. Such a sharp transition of the
inflationary background can trigger the coherent motion of scalar condensates
with effective potentials governed by the rolling rate of the inflaton field.
We show that a scalar condensate carrying (a combination of) baryon or lepton
number can achieve successful baryogenesis through the Affleck-Dine mechanism
from unconventional initial conditions excited by the USR transition. Viable
parameter space for creating the correct baryon asymmetry of the Universe
naturally incorporates the specific limit for PBHs to contribute significantly
to dark matter, shedding light on the cosmic coincidence problem between the
baryon and dark matter densities today.
