F. Cardone et R. Mignani, Energy-dependent description of gravitation supported by an electromagnetic test of local Lorentz invariance, FOUND PH L, 14(4), 2001, pp. 367-376
We put forward a possible intriguing connection between an energy-dependent
metric for gravitation (obtained by fitting the data on the slowing down o
f clocks in the gravitational field of Earth) and the positive experimental
results of a recently proposed electromagnetic test of breakdown of local
Lorentz invariance, based on the detection of a voltage induced by a steady
magnetic field.
