Abstract

We propose a novel scheme to guide cold atoms using a blue-detuned TE 01 doughnut mode in a hollow metallic waveguide, calculate the electromagnetic field distribution of the TE 01 mode in the hollow metallic waveguide, and compare the attenuation characters of the EH 11 and TE 01 mode in the hollow metallic waveguide. We also calculate the optical potential of the TE 01 doughnut mode for two-level 85 Rb atoms and estimate the photon scattering rate. It is found that when the detuning δ = 300 GHz, the photon scattering induced heating can be neglected, and the optical potential ( U max ≈570 mK) of the TE 01 mode is high enough to load cold atoms (120 μK) from a standard magneto-optical trap and to guide them in the hollow metallic waveguide, which is a desirable scheme to realize a computer-controlled atom lithography with an arbitrary pattern.

Atomic (or molecular) guiding using a blue-detuned doughnut mode in a hollow metallic waveguide

Zhengling Wang, Meng Dai, Jianping Yin

We propose a new scheme to guide cold atoms (or molecules) using a blue-detuned TE(01) doughnut mode in a hollow metallic waveguide (HMW), and analyze the electromagnetic field distributions of various modes in the HMW. We calculate the optical potentials of the TE(01) doughnut mode for three-level atoms using dressed-atom approach, and find that the optical potential of the TE(01) mode is high enough to guide cold atoms released from a standard magneto-optical trap. Our study shows that when the input laser power is 0.5W and its detuning is 3GHz, the guiding efficiency of cold atoms in the straight HMW with a hollow radius of 15 microm can reach 98%, and this guiding efficiency will be almost unchanged with the change of curvature radius R of the bent HMW as R > 2cm, which is a desirable scheme to do some atom-optics experiments or realize a computer-controlled atom lithography with an arbitrary pattern. We also analyze the losses of the guided atoms in the HMW due to the spontaneous emission and background thermal collisions and briefly discuss some potential applications of our guiding scheme in atom and molecule optics.

Cold atom guidance in a capillary using blue-detuned, hollow optical modes

J. A. Pechkis, Fredrik K. Fatemi

We demonstrate guiding of cold 85Rb atoms through a 100-micron-diameter hollow core dielectric waveguide using cylindrical hollow modes. We have transported atoms using blue-detuned light in the 1st order, azimuthally-polarized TE01 hollow mode, and the 2nd order hollow modes (HE31, EH11, and HE12), and compared these results with guidance in the red-detuned, fundamental HE11 mode. The blue-detuned hollow modes confine atoms to low intensity along the capillary axis, far from the walls. We determine scattering rates in the guides by directly measuring the effect of recoil on the atoms. We observe higher atom numbers guided using red-detuned light in the HE11 mode, but a 10-fold reduction in scattering rate using the 2nd order modes, which have an r4 radial intensity profile to lowest order. We show that the red-detuned guides can be used to load atoms into the blue-detuned modes when both high atom number and low perturbation are desired.

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.

Guiding and cooling of atoms in an interference field composed of two hollow beams

Zhengling Wang, Jianping Yin, Zhengling Wang

We propose a new scheme to guide and cool three-level alkali-metal atoms in a blue-detuned interference field composed of two counter-propagating doughnut hollow beams, and analyze the intensity distribution of the interference field of the two hollow beams and its intensity gradient one. Our study shows that the high intensity gradient of the interference field is desirable to realize intensity-gradient cooling for the guided atoms, and the minimum optical potential at the nodes of the interference field is high enough to guide almost all atoms released from a standard magneto-optical trap. We also perform Monte-Carlo simulations for dynamic process of the intensity-gradient cooling, and show that an (87)Rb atomic sample with a temperature of 120 muK can be directly cooled to a final equilibrium temperature of 4.71 muK in our guiding scheme.

Generation of One-Dimensional Array of Focused Hollow-Beam Pipes and Its Surface Microscopic Waveguide for Cold Atoms or Molecules

Ji Xian-Ming, Yong Xia, Yin Jian-Ping

We propose a new scheme to guide cold atoms (or molecules) by using a one-dimensional (1D) array of focused hollow-beam pipes generated by the combination of a binary phase grating and a 1D array of micro-cylindrical lenses on the substrate surface. We also calculate the intensity distribution of the focused hollow-beam pipe array and its optical potential for 85 Rb atoms. The result shows that when the blue detuning of the incident beam and its intensity are 10 GHz and 7.0×10 3 W/m 2 respectively, the horizontal dark spot size of each focused hollow-beam pipe and the efficient optical potential are 4.4 μm and ~0.23 mK, which is high enough to guide cold 85 Rb atoms (~20 μK) from a standard optical molasses and then to realize the 1D array of surface atomic waveguides on an atom chip.
