Electrical Conductivity at the Core of a Magnetar
An expression for the electrical conductivity at the core of a magnetar is
derived using Boltzmann kinetic equation with the relaxation time
approximation. The rates for the relevant scattering processes, e.g.,
electron-electron and electron-proton are evaluated in presence of strong
quantizing magnetic fields using tree level diagrams. It is found that in
presence of a strong quantizing magnetic field, electrical conductivity behaves
like a second rank tensor. However, if the zeroth Landau levels are only
occupied by the charged particles, it again behaves like a scaler of a one
dimensional system.Comment: REVTEX File, 4 .eps figures (included
