The Fano resonance for Anderson impurity systems
H. G. Luo, T. Xiang, X. Q. Wang +2
We present a general theory for the Fano resonance in Anderson impurity systems. It is shown that the broadening of the impurity level leads to an additional and important contribu…
Nature of Integer Quantum Hall Transitions
Xiao-Qian Wang
The mapping between the metal-insulator transition of the quantum Hall system and a superfluid-to-insulator transition is revisited based on a disordered anyon model. The one-param…
Low-Lying Energy Properties of a Frustrated Antiferromagnetic Spin- Ladder
Xiaoqun Wang
Using the Density Matrix Renormalization Group method, we determined the phase diagram of a frustrated antiferromagnetic spin- ladder at zero temperature. Two spin-gappe…
Transfer Matrix DMRG for Thermodynamics of One-Dimensional Quantum Systems
Xiaoqun Wang, Tao Xiang
The transfer matrix DMRG method for one dimensional quantum lattice systems has been developed by considering the symmetry property of the transfer matrix and introducing the asymm…
