Topological superconductivity in a topological insulator
Hao Yu, Noah F. Q. Yuan, Wei-Jian Li +6
Topological superconductivity is an exotic quantum phenomenon with coupled nontrivial topological order and superconductivity together. A direct idea for producing topological supe…
Bosonic fractional Chern insulating state at integer fillings in multi-band system
Wei-Wei Luo, Ai-Lei He, Yi-Fei Wang +2
The integer quantum Hall state occurs when the Landau levels are fully occupied by the fermions, while the fractional quantum Hall state usually emerges when the Landau level is pa…
Quasicrystalline Chern Insulators
Ai-Lei He, Lu-Rong Ding, Yuan Zhou +2
Chern insulator or quantum anomalous Hall state is a topological state with integer Hall conductivity but in absence of Landau level. It had been well established on various two-di…
Fractional Chern Insulators in Singular Geometries
Ai-Lei He, Wei-Wei Luo, Yi-Fei Wang +1
The fractional quantum anomalous Hall (FQAH) states or fractional Chern insulator (FCI) states have been studied on two-dimensional (2D) flat lattices with different boundary condi…
Chern Insulators on Singular Geometries
Ai-Lei He, Wei-Wei Luo, Yi-Fei Wang +1
Topological quantum states have been proposed and investigated on two-dimensional flat surfaces or lattices with different geometries like the plane, cylinder and torus. Here, we s…
Variational Monte Carlo study of spin dynamics in underdoped cuprates
Zuo-Dong Yu, Yuan Zhou, Chang-De Gong
The hour-glass-like dispersion of spin excitations is a common feature of underdoped cuprates. It was qualitatively explained by the random phase approximation based on various ord…
