Quantum-Gravity Phenomenology – Electrodynamics and Photons| 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 ξlP
∇2B,
and similarly for ∂B/∂t.
