Applied Atom Interferometry: On the Fringe

We demonstrate a dual-axis accelerometer and gyroscope atom interferometer via cold ensemble exchange [1]. The apparatus is capable of operating in a dynamic environment, due to the short time-of-flight $T \approx 4~\mathrm{ms}$ [2], with sensitivities at $\mathrm{\mu g/\sqrt{Hz}}$ and $\mathrm{\mu rad/s/\sqrt{Hz}}$ levels. Part of the sensitivity losses are mitigated due to operation at a high data-rate [3]. We explore various limitations to operation in a dynamic environment and enhancement of dynamic range using auxiliary sensors.\\[4pt] [1] A. V. Rakholia, H. J. McGuinness, G. W.
