Soliton interferometry with very narrow barriers obtained from spatially dependent dressed states [dataset] Open Access

Bright solitons in atomic Bose-Einstein condensates are a strong candidate for high precision matter-wave interferometry, as their inherent stability against dispersion supports long interrogation times. One analog to a beam splitter for these solitons is a narrow potential barrier. A very narrow barrier is desirable for interferometric purposes, but the width in a typical realisation, using a blue-detuned optical dipole potential, is limited by the wavelength of the laser light. We investigate a soliton interferometry scheme using the geometric scalar potential experienced by atoms in a spatially dependent dark state to overcome this limit. We propose a possible implementation and numerically probe the effects of deviations from the ideal.
