Dynamics of the inflaton scalar field for a certain class of E-model potentials

Vladimir A. Koutvitsky, Eugene M. Maslov

We investigate the dynamics of the inflaton scalar field in a certain class of inflationary E-models that combine the properties of the Starobinsky model and the -attractor mode…

Impact of hypermagnetic fields on relic gravitational waves, neutrino oscillations and baryon asymmetry

Maxim Dvornikov

We study the evolution of random hypermagnetic fields (HMFs) in the symmetric phase of the early universe before the electroweak phase transition. The behavior of HMFs is driven by…

Influence of the hypermagnetic field noise on the baryon asymmetry generation in the symmetric phase of the early universe

Maxim Dvornikov, Victor B. Semikoz

We study a matter turbulence caused by strong random hypermagnetic fields (HMFs ) that influence the baryon asymmetry evolution due to the Abelian anomalies in the symmetric phase…

Cosmological magnetic fields in turbulent matter

Maxim Dvornikov

We study the evolution of magnetic fields in turbulent hot plasma of the early Universe accounting for the chiral magnetic effect. The magnetohydrodynamic turbulence is modeled by…

Influence of the turbulent motion on the chiral magnetic effect in the early Universe

Maxim Dvornikov, Victor B. Semikoz

We study the magnetohydrodynamics of relativistic plasmas accounting for the chiral magnetic effect (CME). To take into account the evolution of the plasma velocity, obeying the Na…

Nonconservation of lepton current and asymmetry of relic neutrinos

Maxim Dvornikov, Victor B. Semikoz

The neutrino asymmetry in the early universe plasma, , is calculated both before and after the electroweak phase transition (EWPT). The leptogenesis before EWPT wi…

Shape of the inflaton potential and the efficiency of the universe heating

A. D. Dolgov, A. V. Popov, A. S. Rudenko

It is shown that the efficiency of the universe heating by an inflaton field depends not only on the possible presence of parametric resonance in the production of scalar particles…

Lepton asymmetry growth in the symmetric phase of an electroweak plasma with hypermagnetic fields versus its washing out by sphalerons

Maxim Dvornikov, Victor B. Semikoz

We study lepton asymmetry evolution in plasma of the early Universe before the electroweak phase transition (EWPT) accounting for chirality flip processes via Higgs decays (inverse…

On ultra-high energy cosmic rays: origin in AGN jets and transport in expanding Universe

V. S. Ptuskin, S. I. Rogovaya, V. N. Zirakashvili

The cosmic ray source spectrum produced by AGN (Active Galactic Nucleus) jets is calculated. A distinctive feature of these calculations is the account for the jet distribution on…

Chern-Simons anomaly as polarization effect

V. B. Semikoz, J. W. F. Valle

The parity violating Chern-Simons term in the epoch before the electroweak phase transition can be interpreted as a polarization effect associated to massless right-handed electron…

Flow of hypermagnetic helicity in the embryo of a new phase in the electroweak phase transition

P. M. Akhmet'ev, V. B. Semikoz, D. D. Sokoloff

The dynamics of the magnetic helicity during the electroweak phase transition in the early Universe is studied. It is shown that the boundary surface between symmetric (hypermagnet…
