Many-Body Coherent Destruction of Tunneling
arXiv:0909.0072 · doi:10.1103/PhysRevLett.103.133002
Abstract
A new route to coherent destruction of tunneling is established by considering a monochromatic fast modulation of the self-interaction strength of a many-boson system. The modulation can be tuned such that only an arbitrarily, a priori prescribed number of particles are allowed to tunnel. The associated tunneling dynamics is sensitive to the odd or even nature of the number of bosons.
