High spatial resolution charge sensing of quantum Hall states
Cheng-Li Chiu, Taige Wang, Ruihua Fan +5
Charge distribution offers a unique fingerprint of important properties of electronic systems, including dielectric response, charge ordering and charge fractionalization. We devel…
Detecting axion dynamics on the surface of magnetic topological insulators
Zhi-Qiang Gao, Taige Wang, Michael P. Zaletel +1
Axions, initially proposed to solve the strong CP problem, have recently gained attention in condensed matter physics, particularly in topological insulators. However, detecting ax…
Higher Hall conductivity from a single wave function: Obstructions to symmetry-preserving gapped edge of (2+1)D topological order
Ryohei Kobayashi, Taige Wang, Tomohiro Soejima +2
A (2+1)D topological ordered phase with U(1) symmetry may or may not have a symmetric gapped edge state, even if both thermal and electric Hall conductivity are vanishing. It is re…
Anomalous Hall Crystals in Rhombohedral Multilayer Graphene II: General Mechanism and a Minimal Model
Tomohiro Soejima, Junkai Dong, Taige Wang +4
We propose a minimal "three-patch model" for the anomalous Hall crystal (AHC), a topological electronic state that spontaneously breaks both time-reversal symmetry and continuous t…
Spontaneous localization at a potential saddle point from edge state reconstruction in a quantum Hall point contact
Liam A. Cohen, Noah L. Samuelson, Taige Wang +7
Quantum point contacts (QPCs) are an essential component in mesoscopic devices. Here, we study the transmission of quantum Hall edge modes through a gate-defined QPC in monolayer g…
