Controlling the Momentum Current of an Off-resonant Ratchet
R. K. Shrestha, J. Ni, W. K. Lam +2
We experimentally investigate the phenomenon of a quantum ratchet created by exposing a Bose-Einstein Condensate to short pulses of a potential which is periodic in both space and…

A cold-atom ratchet interpolating between classical and quantum dynamics
R. K. Shrestha, W. K. Lam, J. Ni +1
We study the crossover between classical and quantum dynamics by observing the behavior of a quantum ratchet created by exposing a Bose-Einstein condensate to short pulses of a pot…

Fidelity of the quantum delta-kicked accelerator
R. K. Shrestha, S. Wimberger, J. Ni +2
The sensitivity of the fidelity in the kicked rotor to an acceleration is experimentally and theoretically investigated. We used a Bose-Einstein condensate exposed to a sequence of…
