ONE THING THAT GENERAL RELATIVITY SAYS
ABOUT PHOTONS IN MATTER
S. ANTOCI AND L. MIHICH
Abstract. Let us abandon for a moment the strict epistemological
standpoint of quantum field theory, that eventually comes to declare
nonsensical any question about the photon posed outside the quantum
theoretical framework. We can then avail of the works by Whittaker et
al. and by Synge about the particle and the wave model of the photon
in the vacuum of general relativity. We can also rely on important
results found by Gordon and by Pham Mau Quan: thanks to Gordon's
discovery of an effective metric these authors have been able to reduce
to the vacuum case several problems of the electromagnetic theory of
dielectrics.
The joint use of these old findings allows one to conclude that a quan-
tum theoretical photon in an isotropic dielectric has a classical simile
only if the dielectric is also homogeneous.
1. Introduction
When writing a paper with the title given above, one is fully aware of the
fact that it will be judged very differently by readers with different epistemo-
