Creation of Dirac neutrinos in a dense medium with time-dependent effective potential
Maxim Dvornikov, S. P. Gavrilov, D. M. Gitman
We consider Dirac neutrinos interacting with background fermions in the frame of the standard model. We demonstrate that a time-dependent effective potential is quite possible in a…
Attractive interaction between ions inside a quantum plasma structure
Maxim Dvornikov
We construct the model of a quantum spherically symmetric plasma structure based on radial oscillations of ions. We suppose that ions are involved in ion-acoustic plasma oscillatio…
Instability of magnetic fields in electroweak plasma driven by neutrino asymmetries
Maxim Dvornikov, Victor B. Semikoz
The magnetohydrodynamics (MHD) is modified to incorporate the parity violation in the Standard Model leading to a new instability of magnetic fields in the electroweak plasma in th…
Magnetic helicity and energy spectra of a solar active region
Hongqi Zhang, Axel Brandenburg, D. D. Sokoloff
We compute for the first time magnetic helicity and energy spectra of the solar active region NOAA 11158 during 11-15 February 2011 at 20^o southern heliographic latitude using obs…
Hypermagnetic helicity evolution in early universe: leptogenesis and hypermagnetic diffusion

The processes responsible for the broad-band radiation of the young supernova remnant Cas A are explored using a new code which is designed for a detailed treatment of the diffusiv…
Relations between strong high-frequency microwave bursts and proton events
V. Grechnev, N. Meshalkina, I. Chertok +1
Proceeding from close association between solar eruptions, flares, shock waves, and CMEs, we analyze relations between bursts at 35 GHz recorded with the Nobeyama Radio Polarimeter…
A Challenging Solar Eruptive Event of 18 November 2003 and the Causes of the 20 November Geomagnetic Superstorm. II. CMEs, Shock Waves, and Drifting Radio Bursts
V. V. Grechnev, A. M. Uralov, I. M. Chertok +7
We continue our study (Grechnev et al. (2013), doi:10.1007/s11207-013-0316-6; Paper I) on the 18 November 2003 geoffective event. To understand possible impact on geospace of coron…
Long-term variations of geomagnetic activity and their solar sources
B. Kirov, V. N. Obridko, K. Georgieva +2
Geomagnetic activity in each phase of the solar cycle consists of 3 parts: (1) a floor below which the geomagnetic activity cannot fall even in the absence of sunspots, related to…
Dark Matter Search Perspectives with GAMMA-400
A. A. Moiseev, A. M. Galper, O. Adriani +44
GAMMA-400 is a future high-energy gamma-ray telescope, designed to measure the fluxes of gamma-rays and cosmic-ray electrons + positrons, which can be produced by annihilation or d…
Microwave Negative Bursts as Indications of Reconnection between Eruptive Filaments and Large-Scale Coronal Magnetic Environment
V. Grechnev, I. Kuzmenko, A. Uralov +2
Low-temperature plasma ejected in solar eruptions can screen active regions as well as quiet solar areas. Absorption phenomena can be observed in microwaves as 'negative bursts' an…

Boris Filippov
A filament eruption on 2010 October 21 observed from three different viewpoints by the Solar Terrestrial Relations Observatory (STEREO) and the Solar Dynamic Observatory (SDO) is a…
Electron and proton acceleration during the first ground level enhancement of solar cycle 24
C. Li, Kazi A. Firoz, L. P. Sun +1
High-energy particles were recorded by near-Earth spacecraft and ground-based neutron monitors (NMs) on 2012 May 17. This event was the first ground level enhancement (GLE) of sola…
