We consider theoretically ultracold interacting bosonic atoms confined to a wire geometry and coupled to the field of an optical cavity. A spin-orbit coupling is induced via Raman transitions employing a cavity mode and a transverse running-wave pump beam; the transition imprints a spatially dependent phase onto the atomic wave function. Adiabatic elimination of the cavity field leads to an effective Hamiltonian for the atomic degrees of freedom with a self-consistency condition. We map the spin-orbit coupled bosonic wire to a bosonic ladder in a magnetic field, by discretizing the spatial dimension. Using the numerical density-matrix renormalization group method, we show that in the continuum limit the dynamical stabilization of a Meissner superfluid is possible for parameters achievable by current experiments.
