  • The spin-orbit interaction is central to the defining characteristics of topological insulators. Here, Jozwiaket al. report a spin-polarized unoccupied surface resonance coevolving with topological surface states from a pair of Rashba-like states through spin-orbit induced band inversion.

  • In a topological insulator, the surface-state electron spins are ‘locked’ to their direction of travel. But when an electron is kicked out by a photon through the photoelectric effect, the spin polarization is not necessarily conserved. In fact, the ejected spins can be completely manipulated in three dimensions by the incident photons.

  • Local symmetry breaking is intrinsic to a variety of unconventional superconductors; however, little is known about how its coexistence with spin-orbit coupling can impact the electronic properties and superconducting order parameter. Here, studying hole-doped bismuth-based cuprate superconductors by spin-resolved ARPES, the authors find an intrinsic momentum-dependent spin-texture coexisting with superconductivity, attributed to local inversion symmetry breaking.
