Contemporary quantum materials research is guided by themes of topology and electronic
correlations. A confluence of these two themes is engineered in moiré materials, an …

Moiré superlattices, the artificial quantum materials, have provided a wide range of
possibilities for the exploration of completely new physics and device architectures. In this …

The integer quantum anomalous Hall (QAH) effect is a lattice analogue of the quantum Hall
effect at zero magnetic field,–. This phenomenon occurs in systems with topologically non …

The interplay between spontaneous symmetry breaking and topology can result in exotic
quantum states of matter. A celebrated example is the quantum anomalous Hall (QAH) state …

In the presence of a large perpendicular electric field, Bernal-stacked bilayer graphene
(BLG) features several broken-symmetry metallic phases,–as well as magnetic-field-induced …

Magnetism in two-dimensional (2D) van der Waals (vdW) materials has recently emerged as
one of the most promising areas in condensed matter research, with many exciting emerging …

The quantum Hall (QH) effect, quantized Hall resistance combined with zero longitudinal
resistance, is the characteristic experimental fingerprint of Chern insulators—topologically …

Rhombohedral-stacked multilayer graphene hosts a pair of flat bands touching at zero
energy, which should give rise to correlated electron phenomena that can be tuned further …

Electronic states in quasicrystals generally preclude a Bloch description, rendering them
fascinating and enigmatic. Owing to their complexity and scarcity, quasicrystals are …

Magic-angle (θ= 1.0 5°) twisted bilayer graphene (MATBG) has shown two seemingly
contradictory characters: the localization and quantum-dot-like behavior in STM …
