QED Energy-Momentum Trace as a Force in Astrophysics
arXiv:0810.1323 · doi:10.1016/j.physletb.2010.02.083
Abstract
We study the properties of the trace $\Tmm$ of the QED energy-momentum tensor in the presence of quasi-constant external electromagnetic fields. We exhibit the origin of $\Tmm$ in the quantum nonlinearity of the electromagnetic theory. We obtain the quantum vacuum fluctuation-induced interaction of a particle with the field of a strongly magnetized compact stellar object.
