Integrated rotation sensing platform based on matter-wave solitons

Matter-wave Sagnac interferometers are capable of extraordinary levels of rotation sensitivity when compared to state-of-the-art fiber optic gyroscopes [1,2]. However, actual implementations of such matter-wave rotation sensors in a compact, integrated platform have remained elusive due to various technical and fundamental considerations. We propose an experimental implementation of a matter-wave Sagnac interferometer based on confinement of an ultracold gas in the evanescent wave optical dipole trap around a microfabricated Silica microresonator. We consider the Sagnac effect on matter-wave solitons created within this ultracold gas. We show that soliton-based rotation sensing can exhibit superior performance compared to conventional matter-wave Sagnac interferometry. We present theoretical and preliminary experimental results of stability, bias and sensitivity of soliton-based rotation sensing. \newline [1] P.
