Quantum-Gravity Phenomenology – Electrodynamics and Photons  

Quantum-Gravity Effects on Electrodynamics > s.a. uncertainty of uncertainty relations; theory and tests of Lorentz symmetry violation; spacetime foam.
* Main predictions: Modified photon dispersion relations, and vacuum birefringence.
* Photon dispersion relation: Without birefringence or anisotropy, and to lowest order in the Planck mass mP, it can be written as ω2 = k2 ± ξ k3/mP.
* Maxwell equations: To lowest order in the Planck length lP, one possible form includes ∂E/∂t = × B − 2 ξlP2B, and similarly for ∂B/∂t.
