Magnetic Bloch States at Integer Flux Quanta Induced by Super-moiré Potential in Graphene Aligned with Twisted Boron Nitride
Yaqi Ma, Meizhen Huang, Xu Zhang +15
Two-dimensional electron systems in both magnetic fields and periodic potentials are described by Hofstadter butterfly, a fundamental problem of solid-state physics. While moiré sy…
The "Sign problem" of the 3rd order anomalous Hall effect in topological magnetic materials
Xu Zhang, Kai Sun, Zi Yang Meng
The anomalous Hall effect (AHE), which provides a bridgeway between the geometry of quantum wavefunctions and transport measurements, has been a key focus of intensive studies. In…
Experimental evidence for Berry curvature multipoles in antiferromagnets
Soumya Sankar, Ruizi Liu, Xue-Jian Gao +12
Berry curvature multipoles appearing in topological quantum materials have recently attracted much attention. Their presence can manifest in novel phenomena, such as nonlinear anom…
Intrinsic nonlinear Hall effect and gate-switchable Berry curvature sliding in twisted bilayer graphene
Meizhen Huang, Zefei Wu, Xu Zhang +8
Though the observation of the quantum anomalous Hall effect and nonlocal transport response reveals nontrivial band topology governed by the Berry curvature in twisted bilayer grap…
