Riemannian light cone from vanishing birefringence in premetric vacuum electrodynamics
We consider premetric electrodynamics with a local and linear constitutive law for the vacuum. Within this framework, we find quartic Fresnel wave surfaces for the propagation of light. If we require vanishing birefringence in vacuum, then a Riemannian light cone is implied. No proper Finslerian structure can occur. This is generalized to dynamical equations of any order.
متن کاملGeneralized Effective Lagrangian from Non-Commutative Electrodynamics and Vacuum Birefringence
The generalized effective Lagrangian of electromagnetic fields motivated by electrodynamics on non-commutative spaces has been considered. We find the canonical and symmetrical energy-momentum tensors and their non-zero traces. The propagation of a linearly polarized laser beam in the external transverse magnetic field is investigated. We evaluate induced ellipticity which allows us to obtain t...
متن کاملThe concept of vacuum in quantum electrodynamics
A re-evaluation of the concept of vacuum in quantum electrodynamics is presented, focusing on the vacuum of the quantized electromagnetic field. In contrast to the ‘nothingness’ associated to the idea of classical vacuum, subtle aspects are found in relation to the vacuum of the quantized electromagnetic field both at theoretical and experimental levels. These are not the usually called vacuum ...
متن کاملVacuum photon splitting in Lorentz-violating quantum electrodynamics.
Radiative corrections arising from Lorentz violation in the fermion sector induce a nonzero amplitude for vacuum photon splitting. At one loop, the on-shell amplitude acquires both CPT-even and CPT-odd contributions forbidden in conventional electrodynamics.
