We consider theoretically ultra-cold interacting bosonic atoms confined to a one-dimensional wire geometry and coupled to the field of an optical cavity. The spin-orbit coupling is induced dynamically via Raman transitions employing a cavity mode and a transverse running wave pump beam. By adiabatic elimination of the cavity field we obtain 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 the dynamical stabilization of a Meissner superfluid is possible in the continuum limit and thermodynamic limit.
