We experimentally demonstrate optical trapping and simultaneous kinematic tracking in three dimensions of a dielectric microparticle using only a single beam. Our approach is based on the nonseparability of polarization and transverse spatial degrees of freedom in cylindrically polarized modes [1,2].
