    "abstract": "We report an experimental investigation of momentum diffusion in the\ndelta-function kicked rotor where time symmetry is broken by a two-period\nkicking cycle and spatial symmetry by an alternating linear potential. We\nexploit this, and a technique involving a moving optical potential, to create\nan asymmetry in the momentum diffusion that is due to the classical chaotic\ndiffusion. This represents a realization of a type of Hamiltonian quantum\nratchet.",
