In General
* Status: 2001, Neutron interferometry sees a statistically significant
violation, but atomic interferometry does not.

Violation > s.a. equivalence principle; quantum

scalar-tensor theories.
* Idea: The validity
of the equivalence principle in quantum theory has been questioned by a number
of authors.
* QED corrections to photon
propagation: In curved spacetime, or in the presence
of some background fields, the effective action for Maxwell fields includes
curvature terms, which amounts to a violation of the equivalence principle,
and in particular predict the possibility of dispersion and superluminal phase
velocities.
@ Arguments questioning the validity: Taylor PRD(79).
@ QED corrections: Shore
