Phys. Rev. A 61, 033614 (2000) [13 pages]Quantum propagation of neutral atoms in a magnetic quadrupole guideSee Also: Erratum Received 28 September 1999; published 17 February 2000 We consider the quantized motion of neutral atoms at very low temperature in a two-dimensional magnetic quadrupole structure formed, for example, by four current-carrying wires along the z direction. The magnetic field B in the guide is proportional to the vector (x,-y). We show that this field can be used to make a single-mode atomic de Broglie waveguide which has bound states of low angular momentum, even though the field at the center of the guide goes to zero. We investigate the spectrum and decay rate of the transverse modes for spin-1/2 and spin-1 atoms. © 2000 The American Physical Society URL:
