3. 2. Atomic transport in optical lattices

   Författare :Henning Hagman; Claude Dion; Daniel Comparat; Umeå universitet; []
   Nyckelord :Ultra-cold atoms; optical lattice; laser cooling; directed transport; Brownian motor; Brownian motion;

   Sammanfattning : This thesis includes both experimental and theoretical investigations of fluctuation-induced transport phenomena, presented in a series of nine papers, by studies of the dynamics of cold atoms in dissipative optical lattices. With standard laser cooling techniques about 108 cesium atoms are accumulated, cooled to a few μK, and transferred into a dissipative optical lattice. LÄS MER
