“…From (2) and (14) we get N max = a 2 ⊥ Θ/(8a sc R c ). For a guide with R c = 5a ⊥ , Θ = π/2 and a ⊥ ranging from 1 µm to 10 µm, N max ranges from 7 to 70 atoms for a condensate of 87 Rb atoms (a sc = 5.77 nm).…”

“…Cold atoms have already been propagated in various guides (see e.g. [1][2][3][4] and references therein); more and more efficient coherent sources of atoms have recently been designed (using various output coupling schemes, see Refs. [5][6][7][8][9]) and continuous guided beams of condensed atoms will be accessible in the near future (see the preparatory study [10]).…”

Bose-Einstein beams: Coherent propagation through a guide

We compute the stationary profiles of a coherent beam of Bose-Einstein condensed atoms propagating through a guide. Special emphasis is put on the effect of a disturbing obstacle present in the trajectory of the beam. The obstacle considered (such as a bend in the guide, or a laser field perpendicular to the beam) results in a repulsive or an attractive potential acting on the condensate. Different behaviors are observed when the beam velocity (with respect to the speed of sound), the size of the obstacle (relative to the healing length) and the intensity and sign of the potential are varied. The existence of bound states of the condensate is also considered.

“…In this aspect of the project It is possible atomic BECs will provide a path to high precision measurement 55 and experimental progress now makes this a real possibility with significant technological applications, particularly for gravimetry. New atom optical devices seek to trap and control atoms along magnetic wire guides fabricated at a micron scale on a substrate using technology borrowed from the microelectronics industry 56 . Such devices may provide a path to new high precision measurement and even quantum computing.…”

Abstract.We are currently in the midst of a second quantum revolution. The first quantum revolution gave us new rules that govern physical reality. The second quantum revolution will take these rules and use them to develop new technologies. In this review we discuss the principles upon which quantum technology is based and the tools required to develop it. We discuss a number of examples of research programs that could deliver quantum technologies in coming decades including; quantum information technology, quantum electromechanical systems, coherent quantum electronics, quantum optics and coherent matter technology.

“…It is now known that this "Fermi-Bose duality" is a very general property of identical particles in 1D, not restricted to the hard-sphere model, and relating strongly interacting bosons to weakly-interacting fermions and vice versa. In recent years this esoteric subject has become highly relevant through experiments on ultracold atomic vapors in atom waveguides [3][4][5][6][7][8][9][10][11]. An understanding of their properties is important for atom interferometry [12,13] and integrated atom optics [11,14,15], which are potentially important for development of ultrasensitive detectors of accelerations and gravitational anomalies.…”

Derivation of effective zero-range one-dimensional (1D) interactions between atoms in tight waveguides is reviewed, as is the Fermi-Bose mapping method for determination of exact and stronglycorrelated many-body ground states of ultracold bosonic and fermionic atomic vapors in such waveguides, including spin degrees of freedom. Odd-wave 1D interactions derived from 3D p-wave scattering are included as well as the usual even-wave interactions derived from 3D s-wave scattering, with emphasis on the role of 3D Feshbach resonances for selectively enhancing s-wave or p-wave scattering so as to reach 1D confinement-induced resonances of the even and odd-wave interactions. A duality between 1D fermions and bosons with zero-range interactions suggested by Cheon and Shigehara is shown to hold for the effective 1D dynamics of a spinor Fermi gas with both even and odd-wave interactions and that of a spinor Bose gas with even and odd-wave interactions, with even(odd)-wave Bose coupling constants inversely related to odd(even)-wave Fermi coupling constants. Some recent applications of Fermi-Bose mapping to determination of many-body ground states of Bose gases and of both magnetically trapped, spin-aligned and optically trapped, spin-free Fermi gases are described, and a new generalized Fermi-Bose mapping is used to determine the phase diagram of ground-state total spin of the spinor Fermi gas as a function of its even and odd-wave coupling constants.
