Abstract: | A novel magnetic trap for confining ultracold neutral atoms in a ring
is proposed. The magnetic trap is generated by a microfabricated
ferromagnetic structure integrated on an “atom chip”.
The structure is based on previously demonstrated fabrication
techniques and is capable of creating tightly confining reciprocal
traps with trap frequencies as large as 50 kHz. Also, the trap
exhibits significantly smaller magnetic field inhomogeneities
compared to other proposals for current-based reciprocal traps.
The suitability of this trap for atom interferometry and the
study of low dimensional ultracold systems is outlined. |
