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.

Microwave spectroscopy of radio-frequency dressed 87Rb (2019)
Journal Article
A. Sinuco-Leon, G., M. Garraway, B., Mas, H., Pandey, S., Vasilakis, G., Bolpasi, V., …Fernholz, T. (2019). Microwave spectroscopy of radio-frequency dressed 87Rb. Physical Review A, 100(5), https://doi.org/10.1103/PhysRevA.100.053416

We study the hyperfine spectrum of atoms of $^{87}$Rb dressed by a radio-frequency field, and present experimental results in three different situations: freely falling atoms, atoms trapped in an optical dipole trap and atoms in an adiabatic radio-fr...

Dispersive detection of radio-frequency-dressed states (2018)
Journal Article
Jammi, S., Pyragius, T., Bason, M. G., Florez, H. M., & Fernholz, T. (2018). Dispersive detection of radio-frequency-dressed states. Physical Review A, 97(4), Article 043416. https://doi.org/10.1103/PhysRevA.97.043416

We introduce a method to dispersively detect alkali atoms in radio-frequency dressed states. In particular, we use dressed detection to measure populations and population differences of atoms prepared in their clock states. Linear birefringence of th...

Towards rotation sensing with a single atomic clock (2016)
Journal Article
Fernholz, T., Stevenson, R., Hush, M. R., Lesanovsky, I., Bishop, T., Gentile, F., …von Klitzing, W. (2016). Towards rotation sensing with a single atomic clock. Proceedings of SPIE, 9900(990007), https://doi.org/10.1117/12.2229878

We discuss a scheme to implement a gyroscopic atom sensor with magnetically trapped ultra-cold atoms. Unlike standard light or matter wave Sagnac interferometers no free wave propagation is used. Interferometer operation is controlled only with stati... Read More about Towards rotation sensing with a single atomic clock.
