## Description

- description: 'Flavor (spin and valley) order plays a critical role in the physics
    of flatband graphene systems, leading for example to Fermi surface reconstructions1–7,
    and quantum anomalous Hall states7–11. Understanding the interplay between flavor
    order and superconductivity stands as a key research goal. Here we establish an
    optical technique that sensitively and selectively detects flavor textures in
    flatband graphene. By performing a systematic study across natural and magic-angle-twisted
    bilayer and trilayer graphene and comparing with theory, we show that it provides
    information that is distinct from and complementary to electrical compressibility
    measurements. The wide-field imaging capability of optical probes allows us to
    obtain spatial maps of flavor orders with high throughput, and with broad temperature
    and device compatibility. '
