Analytic Description of Primordial Black Hole Formation from Scalar Field Fragmentation
Eric Cotner, Alexander Kusenko, Misao Sasaki +1
Primordial black hole (PBH) formation is a more generic phenomenon than was once thought. The dynamics of a scalar field in inflationary universe can produce PBHs under mild assump…
Primordial Black Holes from Inflaton Fragmentation into Oscillons
Eric Cotner, Alexander Kusenko, Volodymyr Takhistov
We show that fragmentation of the inflaton into long-lived spatially localized oscillon configurations can lead to copious production of black holes. In a single-field inflation mo…
Primordial black holes from scalar field evolution in the early universe
Eric Cotner, Alexander Kusenko
Scalar condensates with large expectation values can form in the early universe, for example, in theories with supersymmetry. The condensate can undergo fragmentation into Q-balls…
Primordial black holes from supersymmetry in the early universe
Eric Cotner, Alexander Kusenko
Supersymmetric extensions of the standard model generically predict that in the early universe a scalar condensate can form and fragment into Q-balls before decaying. If the Q-ball…
Astrophysical constraints on dark-matter -balls in the presence of baryon-violating operators
Eric Cotner, Alexander Kusenko
Supersymmetric extensions of the standard model predict the existence of non-topological solitons, -balls. Assuming the standard cosmological history preceded by inflation, -…
Collisional interactions between self-interacting non-relativistic boson stars: effective potential analysis and numerical simulations
Eric Cotner
Scalar particles are a common prediction of many beyond the Standard Model theories. If they are light and cold enough, there is a possibility they may form Bose-Einstein condensat…
