Wegner estimate and Anderson localization for random magnetic fields
Wegner estimate Anderson localization random Schr¨odinger operator
2011/2/25
We consider a two dimensional magnetic Schr¨odinger operator with a spatially stationary random magnetic field. We assume that the magnetic field has a positive lower bound and that it has Fourier mod...
Holographic fermions in external magnetic fields
Holographic fermions external magnetic fields
2010/12/23
We study the Fermi level structure of 2+1-dimensional strongly interacting electron systems in external magnetic field using the AdS/CFT correspondence. The gravity dual of a finite density fermion s...
Formation of Accretion Disks in Close-Binary Systems with Magnetic Fields
Accretion Disks Close-Binary Systems Magnetic Fields
2011/1/10
We have developed a three-dimensional numerical model and applied it to simulate plasma flows in semi-detached binary systems whose accretor possesses a strong intrinsic magnetic field. The model is b...
Possible splitting of deconfinement and chiral transitions in strong magnetic fields in QCD
chiral transitions strong magnetic fields in QCD
2010/12/27
We show that finite-temperature deconfinement and chiral transitions can split in a strong enough magnetic field. The splitting in critical temperatures of these transitions in a constant magnetic fie...
Ultrahigh-energy nuclei, photons, and magnetic fields
Ultrahigh-energy nuclei photons magnetic fields
2011/1/10
Combined recent data from cosmic-ray detectors and gamma-ray detectors have produced some surprising insights regarding the sources of ultrahigh-energy cosmic rays (UHECRs), magnetic fields inside and...

Possible splitting of deconfinement chiral transitions
2011/1/7
We show that finite-temperature deconfinement and chiral transitions can split in a strong enough magnetic field. The splitting in critical temperatures of these transitions in a constant magnetic fie...
Effects of rotation and magnetic fields on the lithium abundance and asteroseismic properties of exoplanet-host stars
magnetic fields the lithium abundance asteroseismic properties
2011/1/11
Aims: The effects of rotation and magnetic fields on the surface abundances of solar-type stars are studied in order to investigate whether the reported difference in lithium content of exoplanet-host...
Trapped, Two-Armed, Nearly Vertical Oscillations in Disks with Toroidal Magnetic Fields
Trapped Two-Armed Nearly Vertical Oscillations
2011/1/13
We have examined trapping of two-armed ($m=2$) nearly vertical oscillations (vertical p-mode) in vertically isothermal ($c_{\rm s}=$ const.) relativistic disks with toroidal magnetic fields. The magne...
Thermal evolution and lifetime of intrinsic magnetic fields of Super Earths in habitable zones
Thermal evolution intrinsic magnetic fields
2011/1/11
We have numerically studied the thermal evolution of various-mass terrestrial planets in habitable zones, focusing on duration of dynamo activity to generate their intrinsic magnetic fields, which may...
The Interplay of Magnetic Fields, Fragmentation and Ionization Feedback in High-Mass Star Formation
Magnetic Fields Fragmentation High-Mass Star Formation
2011/1/13
Massive stars disproportionately influence their surroundings. How they form has only started to become clear recently through radiation gas dynamical simulations. However, until now, no simulation ha...
Aggregation of superparamagnetic colloids in magnetic fields: the quest for the equilibrium state
Aggregation of superparamagnetic magnetic
2010/11/25
Experimental and simulation studies of superparamagnetic colloids in strong external fields have systematically shown an irreversible aggregation process in which chains of particles steadily grow and...
Magnetization and Magnetoresistance of CeRu2Al10 under High Magnetic Fields along c-Axis
CeRu2Al10 Kondo semiconductor pulsed high magnetic field
2010/11/24
We have studied the magnetization and magnetoresistance of CeRu2Al10 in the applied magnetic field H along the c-axis up to ∼ 55 T. The magnetization M at low temperatures shows an H-linear incr...

We show that finite-temperature deconfinement and chiral transitions can split in a strong enough magnetic field. The splitting in critical temperatures of these transitions in a constant magnetic fie...
Prospects for Detection of Exoplanet Magnetic Fields Through Bow-Shock Observations During Transits
planet-star interactions planets and satellites magnetic fields—stars
2010/11/16
An asymmetry between the ingress and egress times was observed in the near-UV light curve
of the transit planet WASP-12b. Such asymmetry led us to suggest that the early ingress in
the UV light curv...
Magnetic fields of Ap stars as a result of an instability
Stars chemically peculiar magnetic fields – instabilities
2010/11/15
Ap star magnetism is often attributed to fossil magnetic fields which have not changed much since the pre-main-sequence epoch of the stars. Stable magnetic field configurations are known which could p...
