N$_f$ = 1 QCD in External Magnetic Fields: Staggered Fermions [PDF]
We investigate N$_f$ = 1 QCD in external magnetic fields on the lattice. The background field is introduced by means of the so-called Schrodinger functional.

Research of spatial distribution of electromagnetic fields of industrial frequency in the central part of the city of Saratov [PDF]
The cartographic research of electric and magnetic fields of industrial frequency in the central part of Saratov was performed. Measurements by means of the Gigahertz Solutions ME 3830 B M/E Analyser were executed in the 177 points within the built-up ...

Magnetic scattering of Dirac fermions in topological insulators and graphene
We study quantum transport and scattering of massless Dirac fermions by spatially localized static magnetic fields. The employed model describes in a unified manner the effects of orbital magnetic fields, Zeeman and exchange fields in topological ...

A Possible Origin of Magnetic Fields in Galaxies and Clusters: Strong Magnetic fields at z~10?
We propose that strong magnetic fields should be generated at shock waves associated with formation of galaxies or clusters of galaxies by the Weibel instability, an instability in collisionless plasmas.

Star Formation and Galaxy Dynamo Equations with Random Coefficients
We study the influence of star formation on magnetic field in galaxies. Two approaches have been used to describe this mechanism. The first one uses some averaged approximate kinematic characteristics that appear in the galactic dynamo equations.

Now it is known about 1212 stars of the main sequence and giants (from them 610 stars - it is chemically peculiarity (CP) stars) for which direct measurements of magnetic fields were spent (Bychkov et al.,2008).

Evolution of magnetic fields in stars across the upper main sequence
To properly understand the physics of upper main sequence stars it is particularly important to identify the origin of their magnetic fields. Recently, we confirmed that magnetic fields appear in Ap stars of mass below 3 M_sun only if they have already ...

Observation of a Distribution of Internal Transverse Magnetic Fields in a Mn12-Based Single Molecule Magnet [PDF]
A distribution of internal transverse magnetic fields has been observed in single molecule magnet (SMM) Mn12-BrAc in the pure magnetic quantum tunneling (MQT) regime. Magnetic relaxation experiments at 0.4 K are used to produce a hole in the distribution

Nonperturbative gravito-magnetic fields
In a cold matter universe, the linearized gravito-magnetic tensor field satisfies a transverse condition (vanishing divergence) when it is purely radiative.

Generation of large-scale magnetic fields by small-scale dynamo in shear flows [PDF]
We propose a new mechanism for turbulent mean-field dynamo in which the magnetic fluctuations resulting from a small-scale dynamo drive the generation of large-scale magnetic fields.
