Parent Berry Curvature and the Ideal Anomalous Hall Crystal
Published 2024-11-01“…We study a model of electrons moving in a parent band of uniform Berry curvature. At sufficiently high parent Berry curvature, we show that strong repulsive interactions generically lead to the formation of an anomalous Hall crystal: a topological state with spontaneously broken continuous translation symmetry. …”
