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...
Geometrical Generation of Cosmic Magnetic Fields within Standard Electromagnetism
Geometrical Generation Cosmic Magnetic Fields Standard Electromagnetism
2010/10/18
We study the evolution of cosmological magnetic fields in FRW models with curved spatial sections and outline a geometrical mechanism for their superadiabatic amplification on large scales. The mechan...
The Effective Longitudinal Dielectric Constant for Plasmas in Inhomogeneous Magnetic Fields
The Effective Longitudinal Dielectric Constant Plasmas Inhomogeneous Magnetic Fields
2010/10/26
We present a detailed derivation of the effective dielectric constant to be used in the dispersion relation for electrostatic waves in the case of a plasma immersed in a inhomogeneous magnetic field, ...
