Testing Atom and Neutron Neutrality with Atom Interferometry
arXiv:0711.4636 · doi:10.1103/PhysRevLett.100.120407
Abstract
We propose an atom-interferometry experiment based on the scalar Aharonov-Bohm effect which detects an atom charge at the 10^{-28}e level, and improves the current laboratory limits by 8 orders of magnitude. This setup independently probes neutron charges down to 10^{-28}e, 7 orders of magnitude below current bounds.
