A schematic illustration of experiment proposal.
We let the two sources be located at points O12 and O34 on the xy-plane respectively and invoke an impenetrable line charge (with charge density ρ) oriented along the z-axis. After the four particles are emitted from the two sources, we then move particle 1 from location O12 to location A along path ℓ1 and move particle 4 from location O34 to meet particle 1 at location A along path ℓ4. The motion of the particles are influenced by the electric field of line charge as shown in Eq. (5) and accordingly the corresponding AC phase shifts are φ1 and φ4 for particles 1 and 4 respectively. Similarly, we move particle 2 from location O12 to location B along path ℓ2 and move particle 3 from location O34 to meet particle 2 at location B along path ℓ3 and the corresponding AC phase shifts are φ2 and φ3 for particles 2 and 3 respectively.
