The paper explores the possibility of explaining the observed dark matter (DM) relic abundance and matter-antimatter asymmetry through the evaporation of primordial black holes (PBHs) beyond the semi-classical approximation. The authors investigate how the memory burden, a quantum effect that stabilizes PBHs, can influence the evaporation process and the resulting particle production. They find that for PBH masses greater than $\mathcal{O}(10^3)$ g, the correct DM abundance can be achieved, while for lighter PBHs ($\lesssim \mathcal{O}(10^3)$ g), the baryon asymmetry can be produced. However, achieving both simultaneously is challenging due to the stringent Lyman-$\alpha$ constraint on warm dark matter mass. The study also examines the impact of memory burden on dark radiation and the induced gravitational waves from PBH density fluctuations, providing a potential window to test the memory-burden effects and constraints on DM mass or leptogenesis scale.The paper explores the possibility of explaining the observed dark matter (DM) relic abundance and matter-antimatter asymmetry through the evaporation of primordial black holes (PBHs) beyond the semi-classical approximation.
