Kondo effect in the helical edge liquid of the quantum spin Hall state
Joseph Maciejko, Chaoxing Liu, Yuval Oreg +3
Following the recent observation of the quantum spin Hall (QSH) effect in HgTe quantum wells, an important issue is to understand the effect of impurities on transport in the QSH r…
A -matrix generalization of the Kitaev model
Congjun Wu, Daniel Arovas, Hsiang-Hsuan Hung
We extend the Kitaev model defined for the Pauli-matrices to the Clifford algebra of -matrices, taking the representation as an example. On a decorated square latti…
Orbital analogue of quantum anomalous Hall effect in -band systems
Congjun Wu
We investigate the topological insulating states of the -band systems in optical lattices induced by the onsite orbital angular momentum polarization, which exhibit gapless edge…
Band Collapse and the Quantum Hall Effect in Graphene
B. Andrei Bernevig, Taylor L. Hughes, Han-Dong Chen +2
The recent Quantum Hall experiments in graphene have confirmed the theoretically well-understood picture of the quantum Hall (QH) conductance in fermion systems with continuum Dira…
Spin Current in Spin-Orbit Coupling Systems
Jiangping Hu, Bogdan A. Bernevig, Congjun Wu
We present a simple and pedagogical derivation of the spin current as the linear response to an external electric field for both Rashba and Luttinger spin-orbital coupling Hamilton…
