Equivalence principle and gravitational redshift.
We investigate leading order deviations from general relativity that violate the Einstein equivalence principle in the gravitational standard model extension. We show that redshift experiments based on matter waves and clock comparisons are equivalent to one another. Consideration of torsion balance tests, along with matter-wave, microwave, optical, and Mössbauer clock tests, yields comprehensi...
متن کاملThe strong equivalence principle from a gravitational gauge structure
Gravitational self-interactions are assumed to be determined by the covariant derivative acting on the Riemann-Christoffel field strength. Once imposed on a metric theory, this Yang-Mills gauge constraint extends the equality of gravitational mass and inertial mass to compact bodies with non-negligible gravitational binding energy. Applied to generalized Brans-Dicke theories, it singles out one...
متن کاملOn the gravitational redshift
The purpose of this paper is twofold to demonstrate that in the gravitational redshift it is the frequency a photon that is constant, and to describe the mechanism responsible for the change of its wavelength. PACS: 04.20.Cv, 04.20.-q It is usually assumed that both frequency and wavelength of a photon in the gravitational redshift change whereas its velocity remains constant. In this note we s...
متن کاملEquivalence Principle and Clocks
String theory suggests the existence of gravitational-strength scalar fields (" dilaton " and " moduli ") whose couplings to matter violate the equivalence principle. This provides a new motivation for high-precision clock experiments, as well as a generic theoretical framework for analyzing their significance.
متن کاملCharge conservation and Equivalence principle
The THǫμ formalism was developed to study nonmetric theories of gravitation. In this letter we show that theories that violate Local Lorentz Invariance (LLI) or Local Position Invariance (LPI) also violate charge conservation. Using upper bounds on this violation we can put very stringent limits to violations of Einstein Equivalence Principle (EEP). These limits, in turn, severely restrict stri...
