On the decoherence effect of a stochastic gravitational perturbation on scalar matter and the possibility of its interferometric detection
arXiv:1912.12732 · doi:10.1103/PhysRevLett.126.200403
Abstract
We present a general master equation for the quantum dynamics of a scalar bosonic particle interacting with an external weak and stochastic gravitational field. The dynamics predicts decoherence in position as well as in momentum. We show how the master equation reproduces the results present in the literature by taking appropriate limits, thus explaining the apparent contradiction in their dynamical description. We apply our model to a matter wave experiment, providing a practical formula for determining of the magnitude of gravitational decoherence. We compare it with the standard experimental sources of decoherence.
arXiv commentThe paper now includes also the analysis for the energy eigenbasis decoherence
