Spin-momentum locking as a source of spin-splitting anisotropy in inverted HgTe quantum wells

open access: goldNew Journal of Physics
We show theoretically that Rashba spin–orbit coupling in gated heterostructures results in strong anisotropy of electron spin splitting. A simple analytical expression for the splitting energy is derived and shown to be in excellent agreement with ...

Properties of the spin-momentum locked state

open access: yesJournal of Physics: Conference Series, 2022
Abstract Spin-momentum locking is becoming a cornerstone for the understanding and applications of novel condensed matter systems. Here we assume that it holds locally in position space and from it predict the existence of a local magnetic field.

Dynamical and topological properties of the spin angular momenta in general electromagnetic fields

open access: yesCommunications Physics, 2023
Spin angular momenta play important roles in light–matter interactions, leading to the emergence of the spin Hall effect and topological quasiparticles in modern optics.

Universal spin-momentum locked optical forces [PDF]

open access: yesApplied Physics Letters, 2016
Evanescent electromagnetic waves possess spin-momentum locking, where the direction of propagation (momentum) is locked to the inherent polarization of the wave (transverse spin). We study the optical forces arising from this universal phenomenon and show that the fundamental origin of recently reported non-trivial optical chiral forces is spin ...

Determination of the Spin Axis in Quantum Spin Hall Insulator Candidate Monolayer WTe_{2}

open access: yesPhysical Review X, 2021
Evidence for the quantum spin Hall effect (QSHE) has been reported in several experimental systems, in the form of edge conductance approaching a quantized value at zero magnetic field.

Tunable spin-valley coupling in layered polar Dirac metals

open access: yesCommunications Materials, 2021
Spin-orbit coupling in non-centrosymmetric crystals gives rise to interesting spin-momentum locking of the Fermi surface. Here, the electronic structure of polar metals BaMnX 2 (X = Bi, Sb) reveals a high sensitivity to X sublattice distortions ...

Universal spin-momentum locking of evanescent waves [PDF]

open access: yesOptica, 2016
We show the existence of an inherent property of evanescent electromagnetic waves: spin-momentum locking, where the direction of momentum fundamentally locks the polarization of the wave. We trace the ultimate origin of this phenomenon to complex dispersion and causality requirements on evanescent waves.

Spin-Momentum Locking Induced Anisotropic Magnetoresistance in Monolayer WTe2 [PDF]

open access: yesNano Letters, 2021
Monolayer WTe2 is predicted to be a quantum spin Hall insulator (QSHI), and its quantized edge transport has recently been demonstrated. However, one of the essential properties of a QSHI, spin-momentum locking of the helical edge states, has yet to be experimentally validated. Here, we measure and observe gate-controlled anisotropic magnetoresistance (
