    "abstract": "We consider the possibility of a control field opening up multiple pathways\nand thereby leading to new interference and coherence effects. We illustrate\nthe idea by considering the $J=1/2\\leftrightarrow J=1/2$ transition. As a\nresult of the additional pathways, we show the possibilities of nonzero\nrefractive index without absorption and gain without inversion. We explain\nthese results in terms of the coherence produced by the opening of an extra\npathway.",
