Title: Optical analogue of the Aharonov-Bohm effect using anisotropic media
Author: Dartora, CA
Nobrega, KZ
Cabrera, GG
Abstract: We show that in the context of paraxial optics, which can be analyzed through a wave equation similar to the non-relativistic Schrodinger equation of quantum mechanics but replacing time t by spatial coordinate z. the existence of a vector potential A(perpendicular to) mimicking the magnetic vector potential in quantum mechanics is allowed by specific gauge symmetries of the optical field in a medium with anisotropic refractive index. In this way, we use Feynman's path integral to demonstrate an optical analogue of the quantum-mechanical Aharonov-Bohm effect, encouraging the search for another optical systems with analogies with more complex quantum field theories.
