Condensate splitting in an asymmetric double well for atom chip based sensors.

摘要: We report on the adiabatic splitting of a Bose-Einstein condensate $^{87}\mathrm{Rb}$ atoms by an asymmetric double-well potential located above edge perpendicularly magnetized TbGdFeCo film atom chip. By controlling barrier height and asymmetry, sensitivity axial process is investigated through observation fractional distribution between left right wells. This constitutes novel sensor for which we infer single shot to gravity fields $\ensuremath{\delta}g/g\ensuremath{\approx}2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$. From simple analytic model, propose improvements chip-based detectors using this demonstrated methodology.
