Scharnhorst effect for a general two-parameter lagrangian density
arXiv:hep-th/0410140 · doi:10.1103/PhysRevD.71.067701
Abstract
We discuss how the propagation of electromagnetic fields described by a general two-parameter lagrangian, which contains the Euler-Heisenberg effective lagrangian and the Born-Infeld lagrangian as particular cases, is affected by a pair of parallel plates that impose boundary conditions in the quantized field. We consider three differents setups, namely: (i) two perfectly conducting plates; (ii) two infinitely permeable plates and (iii) a pair of plates in which one of them is a perfect conductor and the other has an infinite magnetic permeability.
