• Abstract: Vector beams (VBs) with spatially varying polarization have broad applications across various fields of optics. We introduce a novel use of VBs to generate synthetic gauge fields for ultracold atoms. By leveraging VBs' rich tunability, this scheme enables the emergence of angular stripe phases over a significantly expanded parameter range, achieving a three-orders-of-magnitude enhancement in the phase diagram and thereby making experimental observation feasible. It also allows for the creation of topologically nontrivial giant skyrmions in spin space, with tunable topology controlled by VB parameters and without requiring rotation. Our work opens new avenues for utilizing VBs in quantum control of ultracold atoms and the exploration of exotic quantum states and phases.
