Exact results of a hard-core interacting system with a single impurity
You-Quan Li, Zhong-Shui Ma
The quantum-mechanical problem of a many-particle system with a single impurity in one-dimension, interacting by a delta-function, is solved. The wave-function for a bosonic system…

On the Conductance Sum Rule for the Hierarchical Edge States of the Fractional Quantum Hall Effect
Zhong-Shui Ma, Yi-Xin Chen, Zhao-Bin Su
The conductance sum rule for the hierarchical edge channel currents of a Fractional Quantum Hall Effect state is derived analytically within the Haldane-Halperin hierarchy scheme.…
