Probing Kitaev Models on Small Lattices
Han-Dong Chen, B. Wang, S. Das Sarma
We address the following important question: how to distinguish Kitaev models experimentally realized on small lattices from other non-topological interacting spin models. Based on…
Quantum phase diagram of fermion mixtures with population imbalance in one-dimensional optical lattices
B. Wang, Han-Dong Chen, S. Das Sarma
With a recently developed time evolving block decimation (TEBD) algorithm, we numerically study the ground state quantum phase diagram of fermi mixtures with attractive inter-speci…
Exact results on the Kitaev model on a hexagonal lattice: spin states, string and brane correlators, and anyonic excitations
Han-Dong Chen, Zohar Nussinov
In this work, we illustrate how a Jordan-Wigner transformation combined with symmetry considerations enables a direct solution of Kitaev's model on the honeycomb lattice. We (i) ex…
Nature of the Quantum Phase Transition in Quantum Compass Model
Han-Dong Chen, Chen Fang, Jiangping Hu +1
In this work, we show that the quantum compass model on an square lattice can be mapped to a fermionic model with local density interaction. We introduce a mean-field approximation…
Topological Dirac Band Insulators in Three Dimensions and Novel Transport Laws
B. Andrei Bernevig, Han-Dong Chen
This paper has been withdrawn.
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…
