    "abstract": "We propose a simple scheme for highly efficient nonlinear interaction between\ntwo weak optical fields. The scheme is based on the attainment of\nelectromagnetically induced transparency simultaneously for both fields via\ntransitions between magnetically split F=1 atomic sublevels, in the presence of\ntwo driving fields. Thereby, equal slow group velocities and symmetric\ncross-coupling of the weak fields over long distances are achieved. By simply\ntuning the fields, this scheme can either yield giant cross-phase modulation or\nultrasensitive two-photon switching.",
