The Aharonov-Casher effect is a Book I topic in the Quantum Collection. It is a quantum phase effect in which a neutral particle with a magnetic dipole moment acquires a measurable phase while moving through an electric field. The effect is closely related to the Aharonov-Bohm effect, but the roles of charge, magnetic flux, electric field, and magnetic moment are interchanged. It illustrates that quantum phases can depend on electromagnetic potentials and geometry, not only on local forces. In interferometry it provides a way to test geometric phase, gauge structure, and the physical meaning of quantum evolution.
Overview
Placeholder: add a concise introduction explaining the effect, its relation to geometric phase, and why it belongs with quantum dynamics and evolution.
Physical idea
Placeholder: describe the phase acquired by a neutral particle with a magnetic moment moving through an electric field.
Relation to other quantum phase effects
Placeholder: connect this page with the Aharonov-Bohm effect, Berry phase, interferometry, and gauge structure.
Applications and experiments
Placeholder: summarize experimental contexts and links to condensed matter, neutron interferometry, and mesoscopic systems where appropriate.
