Ahranov-Bohm Effect for *Electric* Potential Field?

Click For Summary
SUMMARY

The Aharonov-Bohm (AB) effect has been experimentally validated for magnetic fields, particularly in solenoid configurations. However, the effect of electric potentials alone remains unproven. Current discussions suggest that while some studies reference electric potentials, definitive experimental evidence is lacking. The consensus indicates that advancements in experimental precision are necessary to observe the AB effect in the context of electric potentials.

The AB effect has been proved experimentally many times for the case where the EM field is strictly a magnetic flux in a solenoid. But, from what I have read, the AB effect for just an electric potential alone has not been demonstrated yet. Do you believe the AB effect for electric potentials will eventually be proven? Comments?

Thanks in advance.

Wikipedia links to this study, which includes electric potentials, and claims that another paper (reference 5) saw a direct influence of the electric potential as well.
It's just a matter of experimental precision. The magnetic effect is easier to demonstrate.
