We propose a trap for confining cold neutral atoms in a microscopic ring using a magnetoelectrostatic potential. The trapping potential is derived from a combination of a repulsive magnetic field from a hard drive atom mirror and the attractive potential produced by a charged disk patterned on the hard drive surface. We calculate a trap frequency of $[29.7,42.6,62.8]\phantom{\rule{0.3em}{0ex}}\mathrm{kHz}$ and a depth of $[16.1,21.8,21.8]\phantom{\rule{0.3em}{0ex}}\mathrm{MHz}$ for [ $^{133}\mathrm{Cs}$ , $^{87}\mathrm{Rb}$ , $^{40}\mathrm{K}$ ], and discuss a simple loading scheme and a method for fabrication. This device provides a one-dimensional potential in a ring geometry that may be of interest to the study of trapped quantum degenerate one-dimensional gases.We propose a trap for confining cold neutral atoms in a microscopic ring using a magnetoelectrostatic potential.

We propose and analyze neutral atom traps generated by vortices imprinted by magnetic field pulse sequences in type II superconducting disks and rings. We compute the supercurrent distribution and magnetic field resulting from the vortices in the superconductor. Different patterns of vortices can be written by versatile loading field sequences. We discuss in detail procedures to generate quadrupole traps, self-sufficient traps, and ring traps based on superconducting disks and rings. The ease of creating these traps and the low current noise in supercurrent-carrying structures make our approach attractive for designing atom chip interferometers and probes.We propose and analyze neutral atom traps generated by vortices imprinted by magnetic field pulse sequences in type II superconducting disks and rings.
