Hafele and Keating on a chip: Sagnac interferometry with a single clock (2020)
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.

A Voigt effect based 3D vector magnetometer (2019)
Journal Article
Pyragius, T., Marin Florez, H., & Fernholz, T. (2019). A Voigt effect based 3D vector magnetometer. Physical Review A, 100(2), https://doi.org/10.1103/PhysRevA.100.023416

We describe a method to dispersively detect all three vector components of an external magnetic field using alkali atoms based on the Voigt effect. Our method relies on measuring the linear birefringence of the radio frequency dressed atomic medium v... Read More about A Voigt effect based 3D vector magnetometer.
