G. Papini et al., MAXIMAL ACCELERATION OF PHOTONS WITH EFFECTIVE-MASS - FREQUENCY-SHIFTIN CAVITY RESONATORS, Physics letters. A, 202(1), 1995, pp. 50-53
Some geometrical models with maximal acceleration predict that massive
particles will experience gravitational fields produced by their own
acceleration. The effect is extremely small for most particles. For ph
otons with effective mass produced in cavities the effect shifts the p
eak resonant frequency. This shift is in principle measurable.
