    "abstract": "We consider a new model of quantum walk on a one-dimensional momentum space\nthat includes both discrete jumps and continuous drift. Its time evolution has\ntwo stages; a Markov diffusion followed by localized dynamics. As in the well\nknown quantum kicked rotor, this model can be mapped into a localized\none-dimensional Anderson model. For exceptional (rational) values of its scale\nparameter, the system exhibits resonant behavior and reduce to the usual\ndiscrete time quantum walk on the line.",
