Through a systematic study of rhombohedral and rotationally faulted graphene bilayers and trilayers, we show that when the WSe&lt;sub&gt;2&lt;/sub&gt; is in direct contact with the graphene, the exciton response is most sensitive to the large momentum rearrangement of the Fermi surface, and thus flavor orders. 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.&lt;/p&gt;</description></item></channel></rss>
