Pairing strengths for a two orbital model of the Fe-pnictides
Xiao-Liang Qi, S. Raghu, Chao-Xing Liu +2
Using an RPA approximation, we have calculated the strengths of the singlet and triplet pairing interactions which arise from the exchange of spin and orbital fluctuations for a 2-…
Fractional Charge and Quantized Current in the Quantum Spin Hall State
Xiao-Liang Qi, Taylor L. Hughes, Shou-Cheng Zhang
A profound manifestation of topologically non-trivial states of matter is the occurrence of fractionally charged elementary excitations. The quantum spin Hall insulator state is a…
Quantum Spin Hall Insulator State in HgTe Quantum Wells
Markus Koenig, Steffen Wiedmann, Christoph Bruene +5
Recent theory predicted that the Quantum Spin Hall Effect, a fundamentally novel quantum state of matter that exists at zero external magnetic field, may be realized in HgTe/(Hg,Cd…
Spin Hall effect in a Doped Mott Insulator
Su-Peng Kou, Xiao-Liang Qi, Zheng-Yu Weng
The existence of conserved spin Hall currents is shown in a strongly correlated system without involving spin-orbit coupling. The spin Hall conductivity is determined by intrinsic…
Mutual-Chern-Simons effective theory of doped antiferromagnets
Su-Peng Kou, Xiao-Liang Qi, Zheng-Yu Weng
A mutual-Chern-Simons Lagrangian is derived as a minimal field theory description of the phase-string model for doped antiferromagnets. Such an effective Lagrangian is shown to ret…
