The calculated upper limit Kipol state is used as input to investigate the prospects for achieving Bose-Einstein condensation (BEC). The heating rate of the trap population by secondary collisions of the hot products of the process of ionization—i.

Long-range diatomic s + p potentials of heavy rare gases
Autor: J.G.C. Tempelaars, H. C. W. Beijerinck, M.R. Doery, BJ Boudewijn Verhaar, E.J.D. Vredenbregt
Publikováno v: Physical Review A : Atomic, Molecular and Optical Physics, 57(5), 3603-3620. American Physical Society
We examine the long-range part of the rare-gas diatomic potentials that connect to the $R{(n\ensuremath{-}{1)p}^{5}\mathrm{ns}}+R{(n\ensuremath{-}{1)p}^{5}\mathrm{np}}$ atomic states in the separated atom limit ($n=3,$ 4, 5, and 6 for Ne, Ar, Kr, and

Energy bands and Bloch states in 1D laser cooling and their effects on the velocity distribution
Autor: M.R. Doery, Harold Metcalf, E.J.D. Vredenbregt, M. Widmer, J. Bellanca, T. Bergeman
Publikováno v: Physical Review Letters. 72:2546-2549
We describe calculations that predict and analyze distinctive features in the velocity distribution in 1D laser cooling for light shift potential well depths only a few times the recoil energy. These features can be interpreted in terms of population

Limit on suppression of ionization in metastable neon traps due to long-range anisotropy
Autor: M.R. Doery, S.S. Op de Beek, E.J.D. Vredenbregt, Herman Herman Beijerinck, BJ Boudewijn Verhaar
Publikováno v: Physical Review A : Atomic, Molecular and Optical Physics, 58(5), 3673-3682. American Physical Society
This paper investigates the possibility of suppressing the ionization rate in a magnetostatic trap of metastable neon atoms by spin-polarizing the atoms. Suppression of the ionization is critical for the possibility of reaching Bose-Einstein condensa

High-velocity dark states in velocity-selective coherent population trapping
Autor: M. T. Widmer, T. H. Bergeman, M. J. Bellanca, Harold Metcalf, W. F. Buell, M.R. Doery
Publikováno v: Physical review. A, Atomic, molecular, and optical physics. 53(2)
Some of the most interesting and important topics in the field of optical control of atomic motion occur in the quantum domain. In this domain the motion is described in terms of de Broglie wave fields of massive particles, and the interactions betwe

Bichromatic velocity-selective coherent population trapping
Autor: R. Gupta, Harold Metcalf, M.R. Doery, E.J.D. Vredenbregt, T. Bergeman
Publikováno v: Physical review. A, Atomic, molecular, and optical physics. 51(3)
We propose a scheme to achieve one-dimensional velocity-selective coherent population trapping in a five-level system under two-frequency laser excitation. It may be applied to either D line of alkali-metal atoms. The trapped state is a time-dependen

Measurement of force-assisted population accumulation in dark states
Autor: M. J. Bellanca, M. T. Widmer, W. F. Buell, E.J.D. Vredenbregt, Harold Metcalf, M.R. Doery
Publikováno v: Optics Letters, 21(8), 606-614. Optical Society of America (OSA)
Atoms can be accumulated by velocity-selective coherent population trapping (VSCPT) in dark states of very highly monovelocity, resulting in very narrow distributions. The optical pumping process that permits the population accumulation proceeds by r
