Ioffe-pritchard磁阱
Web15 jun. 2006 · Abstract We demonstrated {delta}-kick cooling of sodium atoms with a three-dimensional anisotropic harmonic potential. The radius and temperature of the atomic cloud oscillated with kick time, indicating that the elongated atomic distribution in phase space rotates in the Ioffe-Pritchard potential. http://websites.umich.edu/~mctp/SciPrgPgs/events/2008/SS08/Lectures/michigancornell2.pdf

WebFigure 1 - Un exemple de piège magnétique couramment utilisé (piège de Ioffe-Pritchard). Ce piège est constitué par quatre fils parallèles, parcourus par des courants deux à deux opposés, qui assurent le confinement transverse des atomes. Le confinement longitudinal provient des deux bobines circulaires, parcourues par un même courant. Web21 mei 2004 · We developed the delta-kick cooling to three dimensions using the Ioffe-Pritchard potential. The alternating oscillation of atomic momentum and size was …
Web15 nov. 2012 · The Ioffe–Pritchard trap is the workhorse of modern cold atom physics. Here, we present a novel Ioffe–Pritchard trap coil configuration based purely on circular coils. By eliminating the traditional Ioffe bars one can increase the gradient and thus the radial trapping frequency by almost a factor 2. Web22 okt. 2002 · Abstract Vortices were imprinted in a Bose-Einstein condensate using topological phases. Sodium condensates held in a Ioffe-Pritchard magnetic trap were transformed from a nonrotating state to one with quantized circulation by adiabatically inverting the magnetic bias field along the trap axis.

Web19 sep. 2007 · We have realized a two-dimensional permanent magnetic lattice of Ioffe-Pritchard microtraps for ultracold atoms. The lattice is formed by a single 300−nm magnetized layer of FePt, patterned using optical lithography. Our magnetic lattice consists of more than 15 000 tightly confining microtraps with a density of 1250traps/mm2.
