On Testing the Equivalence Principle with Extragalactic Bursts
An interesting test of Einstein’s equivalence principle (EEP) relies on the observed lag in arrival times of photons emitted from extragalactic transient sources. Attributing the lag between photons of different energies to the gravitational potential of the Milky Way (MW), several authors derive new constraints on deviations from EEP. It is shown here that potential fluctuations from the large...
متن کاملTesting Einstein's Equivalence Principle With Fast Radio Bursts.
The accuracy of Einstein's equivalence principle (EEP) can be tested with the observed time delays between correlated particles or photons that are emitted from astronomical sources. Assuming as a lower limit that the time delays are caused mainly by the gravitational potential of the Milky Way, we prove that fast radio bursts (FRBs) of cosmological origin can be used to constrain the EEP with ...
متن کاملTesting the Equivalence Principle : Why and How ?
Part of the theoretical motivation for improving the present level of testing of the equivalence principle is reviewed. The general rationale for optimizing the choice of pairs of materials to be tested is presented. One introduces a simpliied rationale based on a trichotomy of competing classes of theoretical models. 1. Why testing the equivalence principle ? Einstein introduced in 1907 1] wha...
متن کاملTesting for Extragalactic Correlations of Gamma-Ray Bursts
If gamma-ray bursts (GRBs) are cosmological they need not necessarily be spatially coincident with a host galaxy—in many cosmological models the progenitors are ejected to large distances from their parent galaxies. While the optical transient of GRB 970228 may be close to a faint galaxy, there are several other galaxies in the field which could be the host if the progenitors are ejected to ∼ 5...
متن کاملTesting the Equivalence Principle in the Quantum Regime
We consider possible tests of the Einstein Equivalence Principle for physical systems in which quantum-mechanical vacuum energies cannot be neglected. Specific tests include a search for the manifestation of non-metric effects in Lamb-shift transitions of Hydrogenic atoms and in anomalous magnetic moments of massive leptons. We discuss how current experiments already set bounds on the violation...
