Edge-mode velocities and thermal coherence of quantum Hall interferometers (2009)
Hu, Zi-Xiang, Rezayi, E. H., Wan, Xin, Yang, Kun
We present comprehensive results on the edge-mode velocities in a quantum Hall droplet with realistic interaction and confinement at various filling fractions. We demonstrate that the charge velocity...
Edge states in a honeycomb lattice: effects of anisotropic hopping and mixed edges (2009)
Dahal, Hari P., Hu, Zi-Xiang, Sinitsyn, N. A., Yang, Kun, Balatsky, A. V.
We study the edge states in graphene in the presence of a magnetic field perpendicular to the plane of the lattice. Most of the works done so far discuss the edge states in either zigzag or armchair...
Quasiparticle tunneling in the Moore-Read fractional quantum Hall State (2009)
Chen, Hua, Hu, Zi-Xiang, Yang, Kun, Rezayi, E. H., Wan, Xin
In fractional quantum Hall systems, quasiparticles of fractional charge can tunnel between the edges at a quantum point contact. Such tunneling (or backscattering) processes contribute to charge...

We present a comprehensive numerical study of a microscopic model of the fractional quantum Hall system at filling fraction $\nu = 5/2$, based on the disc geometry. Our model includes Coulomb...
Trapping Abelian anyons in fractional quantum Hall droplets (2007)
Hu, Zi-Xiang, Wan, Xin, Schmitteckert, Peter
We study the trapping of Abelian anyons (quasiholes and quasiparticles) by a local potential (e.g., induced by an AFM tip) in a microscopic model of fractional quantum Hall liquids with long-range...
Persistent spin current and entanglement in the anisotropic spin ring i (2006)
We investigate the ground state persistent spin current and the pair entanglement in one-dimensional antiferromagnetic anisotropic Heisenberg ring with twisted boundary conditions. Solving Bethe...
Ground state properties of one-dimensional Bose-Fermi mixtures (2006)
Hu, Zi-Xiang, Zhang, Qiu-Lan, Li, You-Quan
Bose-Fermi mixtures in one dimension are studied in detail on the basis of an exact solution. Corresponding to three possible choices of the referecce state in the quantum inverse scattering method,...
