    "abstract": "We have shown that quantum interference in a driven quasi-degenerate\ntwo-level atomic system can be controlled by an externally applied magnetic\nfield. We demonstrate that the mechanism of optical control is based on quantum\ninterference, which allows one to implement both electromagnetically induced\ntransparency and electromagnetically induced absorption in one atomic system.\nDispersion of such the medium allows one to control group velocity of\npropagation of light pulses be ultra-slow or superluminal via applied magnetic\nfield.",
