We realize synthetic azimuthal gauge potentials for Bose-Einstein condensates along with spin-orbital-angular-momentum coupling. This is achieved by engineering atom-light interactions. We characterize the spin textures of the atoms and exploit the azimuthal gauge potential to demonstrate the Hess-Fairbank effect, the analogue of Meissner effect in superconductors. Our demonstration serves as a paradigm to create topological excitations by tailoring atom-light interactions where both types of SO(3) vortices in the
manifold, coreless vortices and polar-core vortices, are created in our experiment. The gauge field in the stationary Hamiltonian opens a path to investigating rotation properties of atomic superfluids under thermal equilibrium.
