Manipulations of cold atoms in a one-dimensional ring lattice

The dynamics of Bose-Einstein condensates in a one-dimensional ring optical lattice is related to the interplay of the open system conditions and the initial atomic distribution. The circulation evaluation model based on the relative atomic density on each site is established to analyze the circulation strength under low dissipation. The direction of the circulation due to the symmetry breaking can be manipulated by changing the primary atomic distribution and the number of lattice sites. The effect of the atomic interaction on the atom flow in the optical ring lattice is analyzed to maintain the current interval rotation behavior.
