Parametric excitation of {sup 87}Rb atoms in a quadrupole-Ioffe-configuration trap

doi:10.1103/PHYSREVA.75.053414

Abstract

We have experimentally studied the parametric excitation of {sup 87}Rb atoms in a quadrupole-Ioffe-configuration trap. The temperature of an atomic cloud and number of trapped atoms versus time and modulation frequency of the parametric excitation field have been measured. We also noticed that the contribution of atomic collisions to the energy distributions can not be ignored in the case of weak excitation, which results in a lower temperature of the atomic cloud than by Gehm et al. [Phys. Rev. A 58, 3914 (1998)] predicted.

Nonadiabatic production of spinor condensates with a quadrupole-Ioffe-configuration trap

Zhang, P. ; Xu, Z. ; You, L. ; ... January 2006 - Physical Review. A

Motivated by the recent experimental observation of multicomponent spinor condensates via a time-dependent quadrupole-Ioffe-configuration trap, we provide a general framework for the investigation of nonadiabatic Landau-Zener dynamics of a hyperfine spin, e.g., from an atomic magnetic dipole moment coupled to a weak time-dependent magnetic (B-) field. The spin flipped population distribution, or the so-called Majorona formula, is expressed in terms of system parameters and experimental observables; thus, the distribution provides much needed insight into the underlying mechanism for the production of spinor condensates due to nonadiabatic level crossings.

Study of the Rabi splitting at the 5P{sub 3/2} {yields} 5D{sub 5/2,3/2} transitions in the {sup 87}Rb atom upon cascade excitation in a magnetooptical trap

Akimov, A V ; Tereshchenko, E O ; Snigirev, S A ; ... February 2010 - Quantum Electronics (Woodbury, N.Y.)

The level splitting appearing upon cascade excitation of the 5D{sub 5/2} and 5D{sub 3/2} levels of the {sup 87}Rb atom in a magnetooptical trap is studied experimentally. The 5S{sub 5/2} and 5P{sub 3/2} levels are coupled by a cooling laser field, the Rabi frequency being comparable with the rate of spontaneous decay of the 5P{sub 3/2} level. The experimental spectral profiles are compared with a theoretical model. (laser spectroscopy)

Coherent population trapping in {sup 87}Rb atoms induced by the optical frequency comb excitation

Aumiler, D. November 2010 - Physical Review. A

The excitation of room-temperature four-level {sup 87}Rb atoms by a train of ultrashort pulses is investigated theoretically in the conditions when the pulse repetition period is shorter than the characteristic atomic relaxation times. It is shown that coherent accumulation of excitation leads to coherent population trapping and electromagnetically induced transparency of the excitation pulses when the pulse repetition rate is a subharmonic of the ground-state hyperfine splitting. It is illustrated how the judicious choice for the frequency comb parameters can provide a means to effectively control the degree of coherence between the ground-state hyperfine levels for selective atomic groups, andmore »« less
