Fractional photon-assisted tunnelling of ultra-cold atoms in periodically shaken double-well lattices

Martin Esmann, Jonathan D. Pritchard, Christoph Weiss

Fractional photon-assisted tunnelling is investigated both numerically and analytically in a double-well lattice. While integer photon-assisted tunnelling is a single-particle effe…
