Bosonic amplification of noise-induced suppression of phase diffusion Academic Article uri icon

abstract

  • Abstract We study the effect of noise-induced dephasing on collisional phase diffusion in the two-site Bose-Hubbard model. Dephasing of the quasimomentum modes may slow down phase diffusion in the quantum Zeno limit. Remarkably, the degree of suppression is enhanced by a bosonic factor of order N/log´╗┐ N as the particle number N increases.
