Journal ArticleDOI
Dissipationless Quantum Spin Current at Room Temperature
TL;DR: In this article, the authors theoretically predict that the electric field can induce a substantial amount of dissipationless quantum spin current at room temperature, in hole-doped semiconductors such as Si, Ge, and GaAs.
Journal ArticleDOI
Phase transition between the quantum spin Hall and insulator phases in 3D: emergence of a topological gapless phase
TL;DR: In this article, a gapless phase between the spin Hall and the insulator phases in 3D was investigated in inversion-asymmetric systems, and it was shown that the existence of such a phase stems from the topological nature of gapless points (diabolical points) in three dimensions, but not in 2D.
Journal ArticleDOI
Hall effect of light.
TL;DR: The semiclassical equation of motion for the wave packet of light is derived taking into account the Berry curvature in momentum-space, which leads to the shift of wave-packet motion perpendicular to the gradient of the dielectric constant, i.e., the polarization-dependent Hall effect of light.
Journal ArticleDOI
Quantum spin Hall effect and enhanced magnetic response by spin-orbit coupling.
TL;DR: It is theoretically predicted that two-dimensional bismuth will show the quantum spin-Hall effect, both by calculating the helical edge states, and by showing the nontriviality of the Z2 topological number.
Journal ArticleDOI
Non-Bloch Band Theory of Non-Hermitian Systems.
Kazuki Yokomizo,Shuichi Murakami +1 more
TL;DR: In this paper, a generalized Bloch band theory in one-dimensional spatially periodic tight-binding models is established. And the Brillouin zone is defined for non-Hermitian systems.
