Quantum spin Hall phases
We review our recent theoretical works on the the quantum spin Hall effect. First we compare edge states in various 2D systems, and see whether they are robust or fragile against perturbations. Through the comparisons we see the robust nature of edge states in 2D quantum spin Hall phases. We see how it is protected by the Z2 topological number, and reveal the nature of the Z2 topological number...
متن کاملQuantum anomalous Hall and quantum spin-Hall phases in flattened Bi and Sb bilayers
Discovery of two-dimensional topological insulator such as Bi bilayer initiates challenges in exploring exotic quantum states in low dimensions. We demonstrate a promising way to realize the Kane-Mele-type quantum spin Hall (QSH) phase and the quantum anomalous Hall (QAH) phase in chemically-modified Bi and Sb bilayers using first-principles calculations. We show that single Bi and Sb bilayers ...
متن کاملImpact of spin-orbit coupling on quantum Hall nematic phases.
Anisotropic charge transport is observed in a two-dimensional (2D) hole system in a perpendicular magnetic field at filling factors nu=7/2, nu=11/2, and nu=13/2 at low temperature. In stark contrast, the transport at nu=9/2 is isotropic for all temperatures. Isotropic hole transport at nu=7/2 is restored for sufficiently low 2D densities or an asymmetric confining potential. The density and sym...
متن کاملSymmetry-protected quantum spin Hall phases in two dimensions.
Symmetry-protected topological (SPT) states are short-range entangled states with symmetry. Nontrivial SPT states have symmetry-protected gapless edge excitations. In 2 dimension (2D), there are an infinite number of nontrivial SPT phases with SU(2) or SO(3) symmetry. These phases can be described by SU(2) or SO(3) nonlinear-sigma models with a quantized topological θ term. At an open boundary,...
متن کاملStriped Quantum Hall Phases
While a large number of fractional quantized Hall states have been discovered in the lowest Landau level, such states become increasingly rare in higher Landau levels. Few quantized Hall states have been observed in the first Landau level (Landau level filling factor 2 ≤ ν < 4) and no such states have so far been found for filling factors ν ≥ 4. Correspondingly, the role of electron-electron in...
