The Rashba effect is quintessential in condensed matter physics, appearing in virtually any electronic heterostructure. Its well-known manifestation is a tangential spin texture. Here, the authors theoretically demonstrate the emergence and engineering of radial Rashba spin textures in twisted van der Waals heterostructures using rigorous first-principles simulations and phenomenological modeling. These predictions offer new opportunities for controlling spin manipulation, as well as tuning correlated states and superconductivity in the van der Waals realm.
