Abstract
We observe the non-Abelian Aharonov–Bohm effect by synthesizing non- Abelian gauge fields in a fiber-optic interferometer, enabled by multiple time-reversal sym- metry breaking in orthogonal bases of the Hilbert space. Based on the realized building blocks of non-Abelian gauge fields, We introduce and study a type of non-Abelian Hof- stadter models.
