Coherent control of quantum transport: modulation-enhanced phase detection and band spectroscopy
arXiv:1210.6829 · doi:10.1140/epjst/e2013-01770-x
Abstract
Amplitude modulation of a tilted optical lattice can be used to steer the quantum transport of matter wave packets in a very flexible way. This allows the experimental study of the phase sensitivity in a multimode interferometer based on delocalization-enhanced Bloch oscillations and to probe the band structure modified by a constant force.
