Signature of chiral superconducting order parameter evidenced in mesoscopic superconductors
Xiaoying Xu, Wei Qin, Yuelin Shen +4
Chiral superconductivity is a novel superconducting phase characterized by order parameters that break the time-reversal symmetry, endowing the state with a definite handedness. Un…
Pressure-Driven Moiré Potential Enhancement and Tertiary Gap Opening in Graphene/h-BN Heterostructure
Yupeng Wang, Jiaqi An, Chunhui Ye +13
Moiré superlattices enable engineering of correlated quantum states through tunable periodic potentials, where twist angle controls periodicity but dynamic potential strength modul…
Prediction of High-Temperature Half Quantum Anomalous Hall Effect in a Semi-magnetic Topological Insulator of MnBiTe/SbTe
M. U. Muzaffar, Kai-Zhi Bai, Wei Qin +6
The classic Thouless-Kohmoto-Nightingale-Nijs theorem dictates that a single electron band of a lattice can only harbor an integer quantum Hall conductance as a multiple of e^2/2h,…
Ferroelectrically Switchable Half-Quantized Hall Effect
M. U. Muzaffar, Kai-Zhi Bai, Wei Qin +5
Integrating ferroelectricity, antiferromagnetism, and topological quantum transport within a single material is rare, but crucial for developing next-generation quantum devices. He…
Quantum phase transition driven by competing intralayer and interlayer hopping in bilayer nickelates
Xiaoyu Zhu, Wei Qin, Ping Cui +1
Bilayer nickelates exhibit high-temperature superconductivity under proper hydrostatic pressure or epitaxial strain, signifying the emergence of quantum phase transitions whose phy…
Topological Flat Minibands and Fractional Chern Insulators in Rashba Systems with Tunable Superlattice Potentials
Bokai Liang, Wei Qin, Zhenyu Zhang
Fractional Chern insulators are interaction-driven topological states that realize the lattice analogue of the fractional quantum Hall effect without external magnetic fields. Here…
