We argue that a primordial black hole is a natural and unique candidate for all dark matter. We show that, in a smooth-hybrid new double inflation model, a right amount of the primordial black holes, with a sharply-defined mass, can be produced at the end of the smooth-hybrid regime, through preheating. We first consider masses < 10−7M⊙ which are allowed by all the previous constraints. We next discuss much heavier mass 105M⊙ hinted at by entropy, and galactic size evolution, arguments. Effects on the running of the scalar spectral index are computed.

• Primordial black holes as generators of cosmic structures (2018, background): “Indeed, many people have argued for a spike or non-Gaussianity in the intermediate mass range (10− 103M ) in order to explain the dark matter with PBHs (Frampton et al. 2010; Byrnes, Copeland & Green 2010; Motohashi & Hu 2017; Garcia-Bellido & Ruiz Morales 2017, 2018).”
• EXPERIMENTAL LIMITS ON PRIMORDIAL BLACK HOLE DARK MATTER FROM THE FIRST 2 YR OF KEPLER DATA (2013, background): “…where one inflation solves the flatness, etc., problems that inflation is invoked to solve, and the other inflationary epoch gives rise to PBHs (Frampton et al. 2010; Kawasaki et al. 1998), which can then become the DM. Recall that one of the initial motivations for the scale-free…”
• Massive Primordial Black Holes as Dark Matter and their detection with Gravitational Waves (2017, background): “Some groups still consider the possibility of low-mass PBH (below planetary size) as the main component of DM [35], although there are very stringent constraints on these, see e.”
• Observable Spectra of Induced Gravitational Waves from Inflation (2012, background): “We also investigated whether this model could maximise the spectrum near k = 105[Mpc−1] since these PBHs would be candidates for seeds of SuperMassive Black Holes [58, 59], however we – 10 – found that this would require a running greater than that allowed by WMAP.”
• Non-Gaussianity and the induced gravitational wave background (2021, background): “Examples of modifications to the minimal slow roll scenario include multifield inflation [98, 99], inflaton couplings leading to particle production [47, 51, 100–106], a plateau in the inflaton potential that causes a period of ultra slow roll [107–110], and a brief downward step in the potential [1”
