Primordial Black Holes from Inflaton Fragmentation into Oscillons
  We show that fragmentation of the inflaton into long-lived spatially
localized oscillon configurations can lead to copious production of black
holes. In a single-field inflation model primordial black holes of sublunar
mass can form, and they can account for all of the dark matter. We also explore
the possibility that solar-mass primordial black holes, particularly relevant
for gravitational wave astronomy, are produced from the same mechanism.
