Revealing quantum geometry effects in magic angle twisted bilayer graphene using the circular photogalvanic effect
Eylon Persky, Leonie Parisot, Minhao He +7
We report a photocurrent studies of a magic angle twisted bilayer graphene device using near infrared light. Through photocurrent imaging and polarization dependence, we separate t…

Optical control of orbital magnetism in magic angle twisted bilayer graphene
Eylon Persky, Minhao He, Jiaqi Cai +4
Flat bands in graphene-based moiré structures host a wide range of emerging strongly correlated and topological phenomena. Optically probing and controlling them can reveal import…
