Hierarchy of quasi-symmetries and degeneracies in chiral crystal materials CoSi
Lun-Hui Hu, Chunyu Guo, Yan Sun +5
In materials, certain approximated symmetry operations can exist in a lower-order approximation of the effective model but are good enough to influence the physical responses of th…
Topological excitonic corner states and nodal phase in bilayer quantum spin Hall insulators
Zheng-Rong Liu, Lun-Hui Hu, Chui-Zhen Chen +2
Interaction induced topological states remain one of the fascinating phases in condensed matter physics. The exciton condensate has recently sparked renewed interest due to the dis…
Interference dislocations in condensate of indirect excitons
J. R. Leonard, Lunhui Hu, A. A. High +5
Phase singularities in quantum states play a significant role both in the state properties and in the transition between the states. For instance, a transition to two-dimensional s…
Anomalous Quantum Oscillations of Interacting Electron-hole Gases in Inverted Type-II InAs/GaSb Quantum Wells
Di Xiao, Lun-Hui Hu, Chao-Xing Liu +1
We report magneto-transport studies of InAs/GaSb bilayer quantum wells in a regime where the interlayer tunneling between the electron and hole gases is suppressed. When the chemic…
Topological Charge/spin density Wave in InAs/GaSb Quantum Wells under an In-plane Magnetic Field
Lun-Hui Hu, Chih-Chieh Chen, Chao-Xing Liu +2
We study interaction effect of quantum spin Hall state in InAs/GaSb quantum wells under an in-plane magnetic field by using the self-consistent mean field theory. We construct a ph…
The effect of in-plane magnetic field and applied strain in quantum spin Hall systems: application to InAs/GaSb quantum wells
Lun-Hui Hu, Dong-Hui Xu, Fu-Chun Zhang +1
Motivated by the recent discovery of quantized spin Hall effect in InAs/GaSb quantum wells\cite{du2013}\cite{xu2014}, we theoretically study the effects of in-plane magnetic fi…
