Observing primordial magnetic fields through Dark Matter
Sabir Ramazanov, Federico R. Urban, Alexander Vikman
Primordial magnetic fields are often thought to be the early Universe seeds that have bloomed into what we observe today as galactic and extra-galactic magnetic fields. Owing to th…
Gravitational reheating and superheavy Dark Matter creation after inflation with non-minimal coupling
E. Babichev, D. Gorbunov, S. Ramazanov +1
We discuss the gravitational creation of superheavy particles in an inflationary scenario with a quartic potential and a non-minimal coupling between the inflaton and the R…
Gravitational misalignment mechanism of Dark Matter production
Eugeny Babichev, Dmitry Gorbunov, Sabir Ramazanov
We consider Dark Matter composed of an oscillating singlet scalar field. On top of the mass term, the scalar is equipped with a potential spontaneously breaking Z_2-symmetry. This…
