Non-AbelianSU(2)gauge fields through density wave order and strain in graphene
Spatially varying strain patterns can qualitatively alter the electronic properties of graphene, acting as effective valley-dependent magnetic fields and giving rise to pseudo-Landau-level (PLL) quantization. Here, we show that the strain-induced magnetic field is one component of a non-Abelian $SU(2)$ gauge field within the low-energy theory of graphene and identify …
