Atom coherence propagation in a magnetic atomic waveguide

Abstract

The quantum motion of atoms in a magnetic waveguide is discussed on the basis of our magnetic atom guidance model. The coherence evolution of atoms initially in the Bose-Einstein condensate (BEC) state during propagation along the waveguide is investigated in detail and the first-order and second-order atomic correlation functions are obtained. It is shown that if the frequency ω 0 of the BEC trap is equal to the frequency ω of the potential in the magnetic waveguide, the atoms will remain in the initial coherent state. If ω 0 and ω are mismatched, the initial coherent properties will be weakened.

We investigate the coherence properties of an atomic beam evaporatively cooled in a magnetic guide, assuming thermal equilibrium in the quantum degenerate regime. The gas experiences two-dimensional, transverse Bose-Einstein condensation rather than a full three-dimensional condensation because of the very elongated geometry of the magnetic guide. First order and second order correlation functions of the atomic field are used to characterize the coherence properties of the gas along the axis of the guide. The coherence length of the gas is found to be much larger than the thermal de Broglie wavelength in the strongly quantum degenerate regime. Large intensity fluctuations present in the ideal Bose gas model are found to be strongly reduced by repulsive atomic interactions; this conclusion is obtained with a one-dimensional classical field approximation valid when the temperature of the gas is much higher than its chemical potential, kBT ≫ |µ|.

Atomic quantum motion and single-mode waveguiding in a hollow metallic waveguide

Zhengling Wang, Jianping Yin

We propose a novel scheme to realize atomic quantum motion, single-mode waveguiding, and coherence propagation by using a blue-detuned TE01 doughnut mode in a hollow metallic waveguide (HMW). In this scheme, ultracold atoms can not only be guided in the dark region of the TE01 mode in the HMW (which will suffer the minimal light shift and the lowest spontaneous emission loss), but also retain some advantages of dark hollow beam atomic guiding (which has a larger hollow radius and a higher vacuum). Our study shows that if the incident angle of the ultracold atoms of Bose-Einstein condensation (BEC) is very small and the deviation of the trapping frequency of the BEC from one of the HMWs is very small, the ultracold atoms may remain in the initial coherent state in the course of atomic coupling from the BEC to the HMW. The ground mode of the matter wave and the degree of first- (or second-) order coherence of guided ultracold atoms can be unchanged during propagation in the straight HMW and almost unchanged for several 10-cm propagation distances with a curvature radius ~1.5 m in the curved HMW.

Propagation of Bose-Einstein Condensates in a Magnetic Waveguide

A. E. Leanhardt, A. P. Chikkatur, D. Kielpinski +4 more

Gaseous Bose-Einstein condensates of 2-3 x 10(6) 23Na atoms were loaded into a microfabricated magnetic trap using optical tweezers. Subsequently, the condensates were released into a magnetic waveguide and propagated 12 mm. Single-mode propagation was observed along homogeneous segments of the waveguide. Inhomogeneities in the guiding potential arose from geometric deformations of the microfabricated wires and caused strong transverse excitations. Such deformations may restrict the waveguide physics that can be explored with propagating condensates. Finer perturbations to the guiding potential fragmented the condensate when it was brought closer to the surface.

Coherent Spin Dynamics of a Spin-1 Bose-Einstein Condensate

M.-S. Chang

Bose-Einstein condensation (BEC) is a phenomenon in which identical bosons occupy the same quantum state below a certain critical temperature. A hallmark of BEC is the coherence between particles every particle shares the same quantum wavefunction and phase. This coherence has been demonstrated for the external (motional) degrees of freedom of the atomic condensates by interfering two condensates. In this thesis, the coherence is shown to extend to the internal spin degrees of freedom of a spin-1 Bose gas evidenced by the observed coherent and reversible spin-changing collisions. The observed coherent dynamics are analogous to Josephson oscillations in weakly connected superconductors and represent a type of matter-wave four-wave mixing. Control of the coherent evolution of the system using magnetic fields is also demonstrated. The studies on spinor condensates begin by creating spinor condensates directly using all-optical approaches that were first developed in our laboratory. All-optical formation of Bose-Einstein condensates (BEC) in 1D optical lattice and single focus trap geometries are developed and presented. These techniques offer considerable flexibility and speed compared to magnetic trap approaches, and the trapping potential can be essentially spin-independent and are ideally suited for studying spinor condensates. Using condensates with well-defined initial non-equilibrium spin configuration, spin mixing of F = 1 and F = 2 spinor condensates of rubidium-87 atoms confined in an optical trap is observed. The equilibrium spin configuration in the F = 1 manifold confirms that 87Rb is ferromagnetic. The coherent spinor dynamics are demonstrated by initiating spin mixing deterministically with a non-stationary spin population configuration. Finally, the interplay between the coherent spin mixing and spatial dynamics in spin-1 condensates with ferromagnetic interactions is investigated.
