Report

Manipulation of a Bose-Einstein condensate by a time-averaged orbiting potential using phase jumps of the rotating field

Autor: Cleary, P. W., Hijmans, T. W., Walraven, J. T. M.

We report on the manipulation of the center-of-mass motion (`sloshing') of a Bose Einstein condensate in a time-averaged orbiting potential (TOP) trap. We start with a condensate at rest in the center of a static trapping potential. When suddenly rep

Report

Time and frequency domain solutions in an optical analogue of Grover's search algorithm

Autor: Hijmans, T. W., Huussen, T. N., Spreeuw, R. J. C.

Publikováno v: J. Opt. Soc. Am. B 24, 214 (2007)

We present new results on an optical implementation of Grover's quantum search algorithm. This extends previous work in which the transverse spatial mode of a light beam oscillates between a broad initial input shape and a highly localized spike, whi

Atomic Deuterium Adsorbed on the Surface of Liquid Helium

Autor: Mosk, A. P., Reynolds, M. W., Hijmans, T. W.

We investigate deuterium atoms adsorbed on the surface of liquid helium in equilibrium with a vapor of atoms of the same species. These atoms are studied by a sensitive optical method based on spectroscopy at a wavelength of 122 nm, exciting the 1S-2

Report

Adiabatically changing the phase-space density of a trapped Bose gas

Autor: Pinkse, P. W. H., Mosk, A., Weidemüller, M., Reynolds, M. W., Hijmans, T. W., Walraven, J. T. M.

Publikováno v: Phys.Rev.Lett.78:990-993,1997

We show that the degeneracy parameter of a trapped Bose gas can be changed adiabatically in a reversible way, both in the Boltzmann regime and in the degenerate Bose regime. We have performed measurements on spin-polarized atomic hydrogen in the Bolt

Report

Influence of radiative interatomic collisions on an atom laser

Autor: Hijmans, T. W., Shlyapnikov, G. V., Burin, A. L.

We discuss the role of light absorption by pairs of atoms (radiative collisions) in the context of a model for an atom laser. The model is applied to the case of VSCPT cooling of metastable triplet helium. We show that, because of radiative collision
