Gravitational Decoherence for Mesoscopic Systems
arXiv:1506.04414 · doi:10.1016/j.physleta.2015.10.064
Abstract
We extend the recent gravitational decoherence analysis of Pikovski et al. to an individual mesoscopic system with internal state characterized by a coherent superposition of energy eigenstates. We express the Pikovski et al. effect directly in terms of the energy variance, and show that the interferometric visibility is bounded from below. Hence unlike collisional decoherence, the visibility does not approach zero at large times, although for a large system it can become very small.
