Spin-charge Separated Solitons in a Topological Band Insulator
Ying Ran, Ashvin Vishwanath, Dung-Hai Lee
In this paper we construct a simple, controllable, two dimensional model based on a topological band insulator. It has many attractive properties. (1) We obtain spin-charge separat…
Domain wall type defects as anyons in phase space
Alexander Seidel, Dung-Hai Lee
We discuss how the braiding properties of Laughlin quasi-particles in quantum Hall states can be understood within a one-dimensional formalism we proposed earlier. In this formalis…
Abelian and Non-abelian Hall Liquids and Charge Density Wave: Quantum Number Fractionalization in One and Two Dimensions
Alexander Seidel, Dung-Hai Lee
Previously we have demonstrated that, on a torus, the abelian quantum hall liquid is adiabatically connected to a charge density wave as the smaller dimension of the torus is varie…
Role of interference in MM-wave driven DC transport in two dimensional electron gas
Dung-Hai Lee, Jon Magne Leinaas
In this paper we point out that in addition to the density of states effect proposed in Ref.\cite{durst,anderson} one should consider the effect of constructive interference betwee…
An Unsettled Issue in the Theory of the Half-Filled Landau Level
Dung-Hai Lee
The purpose of this paper is to identify an unsettled issue in the theory of the half-filled Landau level, and state our point of view.
