This thesis aims to explore intriguing phenomena observed in Bose-Einstein condensates (BEC) subjected to asymmetric optical potentials. The phenomena of interest here is directed transport, wherein the BEC is made to ...

The ratchet effect is the rectified motion of atoms using an unbiased driving force. By ‘’unbiased’’ we mean to say that the time-average is equal to zero. This can be accomplished experimentally using cold atoms in a ...
