Synthetic SU(3) non-Abelian gauge fields in photonic synthetic frequency dimensions
The work proposes realizing SU(3) non-Abelian gauge fields in a photonic synthetic frequency dimension using three coupled ring resonators. This is achieved by engineering mode conversion and introducing color-orbit coupling, which allows for the creation of complex wave dynamics. The findings demonstrate how these engineered fields lead to color-resolved textures and Zitterbewegung-like motion, providing a pathway to study non-Abelian physics in synthetic dimensions.
