Quantum-Mechanical Suppression of Accretion by Primordial Black Holes
Abraham Loeb (Harvard)
TL;DR
This paper explores how quantum mechanics suppresses matter accretion onto primordial black holes within dense environments, impacting their growth and astrophysical effects.
Contribution
It introduces a quantum-mechanical framework for understanding accretion suppression in primordial black holes of specific mass ranges.
Findings
Quantum effects significantly reduce accretion rates.
Suppression varies with black hole mass and environment density.
Implications for primordial black hole evolution and detection.
Abstract
The Schwarzschild radii of primordial black holes (PBHs) in the mass range of 6x10^{14}g to 4x10^{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.
