Ground-State Degeneracy of Correlated Insulators with Edges
Gil Refael, Hsiu-Hau Lin
Using the topological flux insertion procedure, the ground-state degeneracy of an insulator on a periodic lattice with filling factor was found to be at least -fold. App…
Andreev Edge State on Semi-Infinite Triangular Lattice: Detecting the Pairing Symmetry in Na_0.35CoO_2.yH_2O
T. Pereg-Barnea, Hsiu-Hau Lin
We study the Andreev edge state on the semi-infinite triangular lattice with different pairing symmetries and boundary topologies. We find a rich phase diagram of zero energy Andre…
Theory of Ferromagnetism in Diluted Magnetic Semiconductors
Jürgen König, Hsiu-Hau Lin, Allan H. MacDonald
Carrier-induced ferromagnetism has been observed in several (III,Mn)V semiconductors. We review the theoretical picture of these ferromagnetic semiconductors that emerges from a mo…
Anomalous Scaling of the SO(8) Symmetric Phases in the Two-Leg Ladder
Hsiu-Hau Lin
We carry out a complete analytical stability study for the SO(8) symmetric phases in the weakly-interacting two-leg ladder. It is shown that the SO(8) symmetry is robust under gene…
Reply to Comment of Yang, Sun, and Chang on "Theory of Diluted Magnetic Semiconductor Ferromagnetism"
Jürgen König, Hsiu-Hau Lin, Allan H. MacDonald
We reply to the comment cond-mat/0008098 by Yang, Sun, and Chang on our paper "Theory of Diluted Magnetic Semiconductor Ferromagnetism", Phys. Rev. Lett. 84, 5628 (2000).
Resonant Multi-Lead Point-Contact Tunneling
C. Nayak, Matthew P. A. Fisher, A. W. W. Ludwig +1
We analyze a model of resonant point-contact tunneling between multiple Luttinger liquid leads. The model is a variant of the multi-channel Kondo model and can be related to the qu…
