Skyrmion Excitations in Quantum Hall Systems
X. C. Xie, Song He
Using finite size calculations on the surface of a sphere we study the topological (skyrmion) excitation in quantum Hall system with spin degree of freedom at filling factors aroun…
Response Function of the Fractional Quantized Hall State on a Sphere II: Exact Diagonalization
Song He, Steven H. Simon, Bertrand I. Halperin
We study the excitation spectra and the dynamical structure factor of quantum Hall states in a finite size system through exact diagonalization. Comparison is made between the nume…
Tunneling into a two-dimensional electron system in a strong magnetic field
Song He, P. M. Platzman, B. I. Halperin
We investigate the properties of the one-electron Green's function in an interacting two-dimensional electron system in a strong magnetic field, which describes an electron tunneli…
