Fractional spin for quantum Hall effect quasiparticles [PDF]
Nuclear Physics B, 1995 We investigate the issue of whether quasiparticles in the fractional quantum Hall effect possess a fractional intrinsic spin. The presence of such a spin $S$ is suggested by the spin-statistics relation $S= /2 $, with $ $ being the statistical angle, and, on a sphere, is required for consistent quantization of one or more quasiparticles.

Discrete quantum geometry and intrinsic spin Hall effect [PDF]
Physical Review B, 2021 We show that the quantum geometry of the Fermi surface can be numerically described by a 3-dimensional discrete quantum manifold. This approach not only avoids singularities in the Fermi sea, but it also enables the precise computation of the intrinsic Hall conductivity resolved in spin, as well as any other local properties of the Fermi surface.

Fragility of the fractional quantum spin Hall effect in quantum gases
New Journal of Physics, 2014 We consider the effect of contact interaction in a prototypical quantum spin Hall system of pseudo-spin-1/2 particles. A strong effective magnetic field with opposite directions for the two spin states restricts two-dimensional particle motion to the ...

Magic in twisted transition metal dichalcogenide bilayers
Nature Communications, 2021 The e moiré superlattice in twisted 2D structures becomes a highly tunable platform of strongly correlated electron systems. Here, the authors predict rich physics at small twist angles in twisted transition metal dichalcogenide bilayers, including a ...

Robustness of Quantum Spin Hall Effect in an External Magnetic Field [PDF]
, 2014 The edge states in the quantum spin Hall effect are expected to be protected by time reversal symmetry. The experimental observation of the quantized conductance was reported in the InAs/GaSb quantum well {[}Du et al, arXiv:1306.1925{]}, up to a large ...

Effects of spin imbalance on the electric-field driven quantum dissipationless spin current in $p$-doped Semiconductors [PDF]
, 2004 It was proposed recently by Murakami et al. [Science \textbf{301}, 1348(2003)] that in a large class of $p$-doped semiconductors, an applied electric field can drive a quantum dissipationless spin current in the direction perpendicular to the electric ...

Dynamical picture of spin Hall effect based on quantum spin vorticity theory
AIP Advances, 2016 It is proposed that the dynamical picture of the spin Hall effect can be explained as the generation of the spin vorticity by the applied electric field on the basis of the “quantum spin vorticity theory”, which describes the equation of motion of local ...
