    "abstract": "We consider propagation of a paraxial beam carrying the spin angular momentum\n(polarization) and intrinsic orbital angular momentum (IOAM) in a smoothly\ninhomogeneous isotropic medium. It is shown that the presence of IOAM can\ndramatically enhance and rearrange the topological phenomena that previously\nwere considered solely in connection to the polarization of transverse waves.\nIn particular, the appearance of a new-type Berry phase that describes the\nparallel transport of the beam structure along a curved ray is predicted. We\nderive the ray equations demonstrating the splitting of beams with different\nvalues of IOAM. This is the orbital angular momentum Hall effect, which\nresembles Magnus effect for optical vortices. Unlike the recently discovered\nspin Hall effect of photons, it can be much larger in magnitude and is inherent\nto waves of any nature. Experimental means to detect the phenomena is\ndiscussed.",
