Kavli Affiliate: Leon Balents | First 5 Authors: Jia-Xin Zhang, Wen O. Wang, Leon Balents, Lucile Savary, | Summary: The absence of a well-defined Fermi surface in flat-band systems challenges the conventional understanding of instabilities toward Landau order based on nesting. We investigate the existence of an intrinsic nesting structure encoded in the band geometry […]
