摘要：

We analyze a type of cavity, or trap, for atoms: a hollow optical fiber bent into a vertical U shape. The atoms are confined by gravity and by light forces due to the evanescent wave on the fiber's interior surface. A unique feature of this cavity is its mechanical flexibility, which allows tailoring of the gravitational potential experienced by the atoms. In particular a cycloid shape gives simple harmonic motion along the fiber. It can achieve confinement times similar to the parabolic reflector type of gravitational cavity. Quantized motion and an intracavity cooling scheme are considered. © 1995 The American Physical Society.
