Engineered quantum tunnelling in extended periodic potentials
arXiv:0706.0414 · doi:10.1088/1742-6596/67/1/012060
Abstract
Quantum tunnelling from a tilted, but otherwise periodic potential is studied. Our theoretical and experimental results show that, by controlling the system's parameters, we can engineer the escape rate of a Bose-Einstein condensate to an exceptional degree. Possible applications of this atom-optics realization of the open Wannier-Stark system are discussed.
