Implications of primordial black holes on the first stars and the origin of the super--massive black holes
Cosimo Bambi, Douglas Spolyar, Alexander D. Dolgov +2
If the cosmological dark matter has a component made of small primordial black holes, they may have a significant impact on the physics of the first stars and on the subsequent for…
Electrodynamics at non-zero temperature, chemical potential, and Bose condensate
Alexander D. Dolgov, Angela Lepidi, Gabriella Piccinelli
Electrodynamics of charged scalar bosons and spin 1/2 fermions is studied at non-zero temperature, chemical potentials, and possible Bose condensate of the charged scalars. Debye s…
Cosmic antimatter: models and observational bounds
A. D. Dolgov
A model which leads to abundant antimatter objects in the Galaxy (anti-clouds, anti-stars, etc) is presented. Observational manifestations are analyzed. In particular, the model al…
Inhomogeneous baryogenesis, cosmic antimatter, and dark matter
A. D. Dolgov, M. Kawasaki, N. Kevlishvili
A model of inhomogeneous baryogenesis based on the Affleck and Dine mechanism is described. A simple coupling of the scalar baryon field to the inflaton allows for formation of ast…
Cosmology and Neutrino Properties
A. D. Dolgov
This is a brief review for particle physicists on cosmological impact of neutrinos and on restrictions on neutrino properties from cosmology. The paper includes discussion of upper…
Dynamical vacuum energy via adjustment mechanism
A. D. Dolgov, F. R. Urban
A new mechanism of adjustment of vacuum energy down to the observed value from an initially huge one is considered. The mechanism is based on a very strong variation of the gravita…
