Title: Condensate Splitting in an Asymmetric Double Well for Atom Chip Based Sensors

Abstract

We report on the adiabatic splitting of a Bose-Einstein condensate of {sup 87}Rb atoms by an asymmetric double-well potential located above the edge of a perpendicularly magnetized TbGdFeCo film atom chip. By controlling the barrier height and double-well asymmetry, the sensitivity of the axial splitting process is investigated through observation of the fractional atom distribution between the left and right wells. This process constitutes a novel sensor for which we infer a single shot sensitivity to gravity fields of {delta}g/g{approx_equal}2x10{sup -4}. From a simple analytic model, we propose improvements to chip-based gravity detectors using this demonstrated methodology.
