    "abstract": "We study the dynamics of a single excitation in a Heisenberg spin-chain\nsubjected to a sequence of periodic pulses from an external, parabolic,\nmagnetic field. We show that, for experimentally reasonable parameters, a pair\nof counter-propagating coherent states are ejected from the centre of the\nchain. We find an illuminating correspondence with the quantum time evolution\nof the well-known paradigm of quantum chaos, the Quantum Kicked Rotor (QKR).\n  From this we can analyse the entanglement production and interpret the\nejected coherent states as a manifestation of so-called `accelerator modes\u0027 of\na classically chaotic system.",
