The acceleration of a neutron in a static electric field

► Acceleration of a neutron in an E field is orthogonal to velocity. KE is conserved. ► For the Aharonov-Casher (AC) effect, acceleration is 0. ► The AC phase arises from the field term in the canonical momentum. ► In a static B field there is no field term in the canonical momentum. ► In a static B field KE is exchanged with Zeeman energy to conserve energy.
