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.
