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…

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,…

Perfect spin-triplet pairing in two-dimensional Ising superconductors purified by indirect excitons
Chuanyi Zhang, Yu Li, Ping Cui +1
Much research effort has been devoted to interfacial or two-dimensional (2D) superconductors, but the underlying pairing mechanisms and pairing symmetries are highly controversial…
