    "abstract": "We propose a novel trap for confining cold neutral atoms in a microscopic\nring using a magneto-electrostatic potential. The trapping potential is derived\nfrom a combination of a repulsive magnetic field from a hard drive atom mirror\nand the attractive potential produced by a charged disk patterned on the hard\ndrive surface. We calculate a trap frequency of [29.7, 42.6, 62.8] kHz and a\ndepth of [16.1, 21.8, 21.8] MHz for [133Cs, 87Rb, 40K], and discuss a simple\nloading scheme and a method for fabrication. This device provides a\none-dimensional potential in a ring geometry that may be of interest to the\nstudy of trapped quantum degenerate one-dimensional gases.",
