Quantum Walks of kicked Bose-Einstein condensates
arXiv:1802.05476 · doi:10.1088/1751-8121/aac5d5
Abstract
We analytically investigate the recently proposed and implemented discrete-time quantum walk based on kicked ultra-cold atoms. We show how the internal level structure of the kicked atoms leads to the emergence of a relative light-shift phase immediately relevant for the experimental realization. Analytical solutions are provided for the momentum distribution for both the case of quantum resonance and the near-resonant quasimomenta.
