Spin-charge separation and quantum spin Hall effect of $$\beta$$ β -bismuthene [PDF]
Scientific Reports, 2023 Multiple works suggest the possibility of classification of quantum spin Hall effect with magnetic flux tubes, which cause separation of spin and charge degrees of freedom and pumping of spin or Kramers-pair. However, the proof of principle demonstration

Higher-order quantum spin Hall effect in a photonic crystal [PDF]
Nature Communications, 2020 The quantum spin Hall effect is limited to one-dimensional lower boundary states which limits the possibilities for its exploitation in photonic devices.

Quantum spin Hall effect in magnetic graphene [PDF]
Nature CommunicationsA promising approach to attain long-distance coherent spin propagation is accessing topological spin-polarized edge states in graphene. Achieving this without external magnetic fields necessitates engineering graphene band structure, obtainable through ...

Analytical theory and possible detection of the ac quantum spin Hall effect [PDF]
Scientific Reports, 2017 We develop an analytical theory of the low-frequency ac quantum spin Hall (QSH) effect based upon the scattering matrix formalism. It is shown that the ac QSH effect can be interpreted as a bulk quantum pumping effect. When the electron spin is conserved,

Quantum Spin Hall Effect [PDF]
Physical Review Letters, 2005 The quantum Hall liquid is a novel state of matter with profound emergent properties such as fractional charge and statistics. Existence of the quantum Hall effect requires breaking of the time reversal symmetry caused by an external magnetic field.

Hierarchical wave function, Fock cyclic condition and spin-statistics relation in the spin-singlet fractional quantum Hall effect [PDF]
, 1993 We construct the hierarchical wave function of the spin-singlet fractional quantum Hall effect, which turns out to satisfy Fock cyclic condition. The spin-statistics relation of the quasi-particles in the spin-singlet fractional quantum Hall effect is ...

Electrical polarization of nuclear spins in a breakdown regime of quantum Hall effect [PDF]
, 2006 We have developed a method for electrical polarization of nuclear spins in quantum Hall systems. In a breakdown regime of odd-integer quantum Hall effect (QHE), excitation of electrons to the upper Landau subband with opposite spin polarity dynamically ...

Quantum Spin Hall Effect in Graphene [PDF]
Physical Review Letters, 2005 We study the effects of spin orbit interactions on the low energy electronic structure of a single plane of graphene. We find that in an experimentally accessible low temperature regime the symmetry allowed spin orbit potential converts graphene from an ...

An approach to the QHE in 3D electron systems [PDF]
Scientific ReportsWe present a theoretical framework for describing the integer quantum Hall effect (IQHE) in three-dimensional (3D) electron systems. This work extends our previous single-electron approach, originally applied to two-dimensional (2D) systems such as ...

Large N spin quantum Hall effect [PDF]
Nuclear Physics B, 2001 We introduce a large N version of the spin quantum Hall transition problem. It is formulated as a problem of Dirac fermions coupled to disorder, whose Hamiltonian belong to the symmetry class C.
