Resonant amplification of magnetic fields from chiral currents in spacetimes with torsion    [PDF]

L C Garcia de Andrade

Resonant amplification of magnetic fields in spacetimes with torsion are investigated by solving the Heisenberg-Ivanenko nonlinear spinor equation. It is shown that torsion is helicity dependent and that the magnetic fields can be resonantly amplified and that the spinor solution leads to an amplification of the magnetic field dependant of the sign of helicity. The QCD domain wall case with torsion is also investigated and the results compared with recent results by Forbes and Zhitnitski (PRL (2001)).
