Journal Article
Johnson, J., Foxon, B., Atkocius, V., Gentile, F., Jammi, S., Poulios, K., & Fernholz, T. (2020). Hafele and Keating on a chip: Sagnac interferometry with a single clock. Proceedings of SPIE, 11296, https://doi.org/10.1117/12.2552686

We describe our progress in the development of an atom based rotation sensor, which employs state-dependent trapping potentials to transport ultracold atoms along a closed path and perform Sagnac interferometry. Whilst guided atom interferometers are... Read More about Hafele and Keating on a chip: Sagnac interferometry with a single clock.

Controlling the dynamical scale factor in a trapped atom Sagnac interferometer (2020)
Journal Article

Sagnac interferometers with massive particles promise unique advantages in achieving high-precision measurements of rotation rates over their optical counterparts. Recent proposals and experiments are exploring nonballistic Sagnac interferometers whe... Read More about Controlling the dynamical scale factor in a trapped atom Sagnac interferometer.
