Abstract
We propose a robust scheme that creates a toroidal magnetic potential on a
single-layer atom chip. The wire layout consists of two interleaved Archimedean spirals,
which avoids the trapping perturbation caused by the input and output ports. By using a
rotation bias field, the minimum of the time-averaged orbiting potential is lifted from
zero, and then a relatively smooth and harmonic ring trap is formed. The location of the
waveguide is immune to the magnetic variations, as it is only determined by the wire
layout. The ring waveguide offers an ideal solution to developing a compact and portable
atomic gyroscope.
