Chiral Surface Wave propagation with Anomalous Spin-momentum Locking [PDF]
ACS Photonics, 2021 The ability to control the directionality of surface waves by manipulating its polarization has been of great significance for applications in spintronics and polarization-based optics. Surface waves with evanescent tails are found to possess an inherent in-plane transverse spin which is dependent on the propagation direction while an out-of-plane ...

Hybrid Spin and Anomalous Spin-Momentum Locking in Surface Elastic Waves [PDF]
Physical Review Letters, 2023 Transverse spin of surface waves is a universal phenomenon which has recently attracted significant attention in optics and acoustics. It appears in gravity water waves, surface plasmon-polaritons, surface acoustic waves, and exhibits remarkable intrinsic spin-momentum locking, which has found useful applications for efficient spin-direction couplers ...

Multi-Terminal Spin Valve on Channels with Spin-Momentum Locking. [PDF]
Sci Rep, 2016 AbstractIt is experimentally established that charge current flowing in a channel with spin-momentum locking such as topological insulator surface states or Rashba interfaces induces a spin voltage, which can be electrically measured with a ferromagnetic contact along the current path.

Probing the Spin-Momentum Locking on Rashba Surfaces via Spin Current. [PDF]
ACS Appl Mater InterfacesIn this work, we explore the intriguing spin-momentum locking phenomenon within the Rashba states of antimony (Sb) films. By combining spin pumping with the flow of an external charge current, we reveal the topological properties of surface states in Sb films.

Observation of spin-momentum-layer locking in centrosymmetric BiOI [PDF]
Physical Review Letters, 2020 The spin polarization in nonmagnetic materials is conventionally attributed to the outcome of spin-orbit coupling when the global inversion symmetry is broken. The recently discovered hidden spin polarization indicates that a specific atomic site asymmetry could also induce measurable spin polarization, leading to a paradigm shift in research on ...

Twist engineering induced spin-orbit coupling for photosynthesis of ethane from carbon dioxide and water [PDF]
Nature CommunicationsHarnessing sunlight, carbon dioxide, and water to produce two-carbon products is promising but constrained by sluggish kinetics and high carbon–carbon coupling barriers.

Kondo effect under arbitrary spin-momentum locking [PDF]
The Kondo effect originates from the spin exchange scattering of itinerant electrons with a localized magnetic impurity. Here, we consider generalization of Weyl-type electrons with their spin locked on a spherical Fermi surface in an arbitrary way and study how such spin-momentum locking affects the Kondo effect.

Spin-momentum locked modes on anti-phase boundaries in photonic crystals
Optics Express, 2020 An anti-phase boundary is formed by shifting a portion of photonic crystal lattice along the direction of periodicity. A spinning magnetic dipole is applied to excite edge modes on the anti-phase boundary. We show the unidirectional propagation of the edge modes which is also known as spin-momentum locking.
