Gravitational Redshift Induces Quantum Interference
نویسندگان
چکیده
We use quantum field theory in curved spacetime to show that gravitational redshift induces a unitary transformation on the state of propagating photons. This occurs for realistic photons characterized by finite bandwidth, while ideal with sharp frequencies do not transform unitarily. find is mode-mixing operation, and we devise protocol exploits gravity induce Hong-Ou-Mandel-like interference effect two Testing results this work can provide demonstration spacetime.

On 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 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 کاملForce-free gravitational redshift: proposed gravitational Aharonov-Bohm experiment.
We propose a feasible laboratory interferometry experiment with matter waves in a gravitational potential caused by a pair of artificial field-generating masses. It will demonstrate that the presence of these masses (and, for moving atoms, time dilation) induces a phase shift, even if it does not cause any classical force. The phase shift is identical to that produced by the gravitational redsh...
متن کاملGravitational Lensing of High Redshift Sources
The combination of deep exposures and high resolution offered by telescopes in space allows the detection of lensing over a wide range of source redshifts and lens masses. As an example, we model a lens candidate found in the southern Hubble Deep Field. The system consists of a source galaxy lensed into an arc, 0. 9 from an elliptical galaxy. The photometric redshift of 0.6 for the lens galaxy ...
متن کاملDetecting the Gravitational Redshift of Cluster Gas.
We examine the gravitational redshift of radiation emitted from within the potential of a cluster. Spectral lines from the intracluster medium (ICM) are redshifted in proportion to the emission-weighted mean potential along the line of sight, amounting to approximately 50 km s-1 at a radius of 100 kpc h-1, for a cluster dispersion of 1200 km s-1. We show that the relative redshifts of different...
