1307.4654 (A. Steyerl et al.)

Geometric phases in electric dipole searches with spin-1/2 particles
from spin dependent Schrödinger equation

A. Steyerl, C. Kaufman, G. Müller, S. S. Malik, A. M. Desai
Geometric phases of trapped particles have been recognized as potential sources of false signals in experiments searching for a permanent electric dipole moment of the neutron. We present a new analysis that treats the spin fully quantum mechanically and uses the same model system as previous works based on semi-classical methods. The results are similar but exhibit significant differences in some respects.
