Half-period Aharonov-Bohm oscillations in disordered rotating optical ring cavities

TL;DR

This paper explores the analogy between rotating optical ring cavities and magnetic systems, revealing that disordered optical rings can exhibit Aharonov-Bohm-like oscillations with respect to rotation speed, akin to mesoscopic electronic effects.

Contribution

It demonstrates the optical analog of the Al'tshuler-Aronov-Spivak effect in disordered rotating ring cavities, linking optical phenomena to mesoscopic physics concepts.

Findings

Disordered optical ring cavities show periodic oscillations with rotation.

Analogies between Maxwell equations in rotating frames and Schrödinger equations are established.

Optical Aharonov-Bohm oscillations depend on angular velocity.

Abstract

There exists an analogy between Maxwell equations in a rotating frame and Schr\"odinger equation for a charged particle in the presence of a magnetic field. We exploit this analogy to point out that electromagnetic phenomena in the rotating frame, under appropriate conditions, can exhibit periodicity with respect to the angular velocity of rotation. In particular, in disordered ring cavities one finds the optical analog of the Al'tshuler-Aronov-Spivak effect well known in mesoscopic physics of disordered metals.
