Gravitational decoherence of atomic interferometers
We study the decoherence of atomic interferometers due to the scattering of stochastic gravitational waves. We evaluate the ‘direct’ gravitational effect registered by the phase of the matter waves as well as the ‘indirect’ effect registered by the light waves used as beam-splitters and mirrors for the matter waves. Considering as an example the space project HYPER, we show that both effects ar...
متن کاملA universal test for gravitational decoherence
Quantum mechanics and the theory of gravity are presently not compatible. A particular question is whether gravity causes decoherence. Several models for gravitational decoherence have been proposed, not all of which can be described quantum mechanically. Since quantum mechanics may need to be modified, one may question the use of quantum mechanics as a calculational tool to draw conclusions fr...
متن کاملQuantum gravitational decoherence of matter waves
One of the biggest unsolved problems in physics is the unification of quantum mechanics and general relativity. The lack of experimental guidance has made the issue extremely evasive, though various attempts have been made to relate the loss of matter wave coherence to quantum spacetime fluctuations. We present a new approach to the gravitational decoherence near the Planck scale, made possible...
متن کاملSpin Decoherence in a Gravitational Field
We discuss a mechanism of spin decoherence in gravitation within the framework of general relativity. The spin state of a particle moving in a gravitational field is shown to decohere due to the curvature of spacetime. As an example, we analyze a particle going around a static spherically-symmetric object. PACS: 03.65.Ta, 04.20.-q, 03.67.-a
متن کاملDecoherence and quantum mechanics in a gravitational field
Quantum mechanical interference of wave functions leads to some difficulties if a probability density is considered as a source of gravity. We show that an introduction of a quantum energy-momentum tensor as a source term in Einstein equations can be consistent with general relativity if the gravitational waves are quantized. PACS numbers:04.60.+n,03.65.-w,03.65.Bz
