Suppression of collision-induced dephasing by periodic, erratic, or noisy driving Academic Article uri icon

abstract

  • Abstract We compare different driving scenarios for controlling the loss of single-particle coherence of an initially coherent preparation in the vicinity of the hyperbolic instability of the two-mode Bose-Hubbard model. In particular, we contrast the quantum Zeno suppression of decoherence by broad-band erratic or noisy driving, with the Kapitza effect obtained for high frequency periodic monochromatic driving.
