Quantum memory burden effect can greatly extend PBH lifetimes
Lighter PBHs could be sole dark matter source with this effect
Also calculate dark matter abundance from PBH particle decay
Wide parameter space fits dark matter abundance with burden effect

Quantum effects extend primordial black hole lifetimes as dark matter candidates
This paper explores how quantum effects like the 'memory burden' could significantly extend the lifetimes of primordial black holes (PBHs), possibly allowing lighter PBHs to comprise all dark matter. The authors calculate dark matter abundance from both extended-lifetime PBHs and their Hawking radiation decay products.
