Abstract
We propose a scheme to exhibit a Stern–Gerlach effect of -component () high-dimensional ultraslow optical solitons in a coherent atomic system with -pod level configuration via electromagnetically induced transparency (EIT). Based on Maxwell–Bloch equations, we derive coupled -dimensional nonlinear Schrödinger equations governing the spatial-temporal evolution of probe-field envelopes. We show that under EIT conditions significant deflections of the components of coupled ultraslow optical solitons can be achieved by using a Stern–Gerlach gradient magnetic field. The stability of the ultraslow optical solitons can be realized by an optical lattice potential contributed from a far-detuned laser field.
