Toward a global phase diagram of the fractional quantum anomalous Hall effect
Aidan P. Reddy, Liang Fu
Recent experiments on the twisted semiconductor bilayer system MoTe have observed integer and fractional quantum anomalous Hall effects, which occur in topological moiré ban…
Strong-coupling phases of trions and excitons in electron-hole bilayers at commensurate densities
David D. Dai, Liang Fu
We introduce density imbalanced electron-hole bilayers at a commensurate 2 : 1 density ratio as a platform for realizing novel phases involving electrons, excitons and trions. Thre…
Quantum metric nonlinear Hall effect in a topological antiferromagnetic heterostructure
Anyuan Gao, Yu-Fei Liu, Jian-Xiang Qiu +28
Quantum geometry - the geometry of electron Bloch wavefunctions - is central to modern condensed matter physics. Due to the quantum nature, quantum geometry has two parts, the real…
Zero-field composite Fermi liquid in twisted semiconductor bilayers
Hart Goldman, Aidan P. Reddy, Nisarga Paul +1
Recent experiments have produced evidence for fractional quantum anomalous Hall (FQAH) states at zero magnetic field in the semiconductor moiré superlattice system MoTe. Her…
Fundamental bound on topological gap
Yugo Onishi, Liang Fu
We provide a universal tight bound on the energy gap of topological insulators by exploring relationships between topology, quantum geometry, and optical absorption. Applications o…
Colossal nonreciprocal Hall effect and broadband frequency mixing due to a room temperature nonlinear Hall effect
Lujin Min, Yang Zhang, Zhijian Xie +8
Nonreciprocal (NR) charge transport in quantum materials has attracted enormous interest since it offers an avenue to investigate quantum symmetry related physics and holds many pr…
