Lifting the spin-momentum locking in ultra-thin topological insulator films [PDF]
Advanced Quantum Technologies, 2021 Abstract 3D topological insulators are known to carry 2D Dirac‐like topological surface states in which spin‐momentum locking prohibits backscattering. When thinned down to a few nanometers, the hybridization between the topological surface states at the top and bottom surfaces results in a topological quantum ...

Spin-momentum locking breakdown on plasmonic metasurfaces [PDF]
Physical Review B, 2023 We present a scattering formalism to analyze the spin-momentum locking in structured holey plasmonic metasurfaces. It is valid for any unit cell for arbitrary position and orientation of the holes. The spin-momentum locking emergence is found to originate from the unit cell configuration.

Field-Effect Josephson Diode via Asymmetric Spin-Momentum-Locking States [PDF]
Physical Review Applied, 2022 Recent breakthroughs in Josephson diodes dangle the possibility of extending conventional non-reciprocal electronics into the realm of superconductivity. While a strong magnetic field is recognized for enhancing diode efficiency, it concurrently poses a risk of undermining the essential superconductivity required for non-dissipative devices.
