Quantum-mechanical Suppression of Accretion by Primordial Black Holes

Abstract

The Schwarzschild radii of primordial black holes (PBHs) in the mass range of 6 × 10 ^14 –4 × 10 ^19 g match the sizes of nuclei to atoms. I discuss the resulting quantum-mechanical suppression in the accretion of matter by PBHs in dense astrophysical environments, such as planets or stars.
