WebOct 5, 2004 · We study in detail the mechanisms causing dephasing of hyperfine coherences of cesium atoms confined by a far off-resonant standing wave optical dipole trap [S. Kuhr et al., Phys. Rev. Lett. 91, 213002 (2003)]. Using Ramsey spectroscopy and spin echo techniques, we measure the reversible and irreversible dephasing times of the … WebJan 12, 2001 · We describe an experiment in which 3 × 10 7 Cs atoms are loaded into a 400 μ m crossed beam far-off-resonant trap (FORT) that is only 2 μ K deep.

The differential light shifts between the 1 S 0 and the 3 D 2 states in a far-off resonant trap at 532 nm are also measured. For the spectroscopy, we developed simple, narrow-linewidth, and long … mtn self service password

WebAug 14, 2014 · A far-off-resonance optical trap for a Ba. ion. Optical trapping and ions combine unique advantages of independently striving fields of research. Light fields can form versatile potential landscapes, such as optical lattices, for neutral and charged atoms, avoiding detrimental implications of established radiofrequency (rf) traps while ... WebOptical far-off-resonance traps have been dem-onstrated for confining arbitrary atomic ground states in nearly identical potentials @5,6# and for optical lattices @7#. Multiple spin condensates have been stored in a shallow far-off-resonance trap to study interactions in the quantum de-generate regime @8#. These traps also offer an attractive pos- WebFar-off-resonant light traps (FORT) were used for knowing the loading and compressing Cs atoms. 3×10 7 Cs atoms were loaded into a 400 μm crossed beam far-off-resonant trap (FORT). Atoms in the FORT were compressed to a spatial density of 2×10 13 atoms/cm 3, and spontaneous emission in the FORT was negligible. how to make sand in minecraft
