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.

Voigt-effect-based three-dimensional vector magnetometer (2019)
Journal Article

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 Voigt-effect-based three-dimensional vector magnetometer.

Interactions between a water molecule and C 60 in the endohedral fullerene H2O@C60 (2019)
Journal Article
Rashed, E., & Dunn, J. L. (2019). Interactions between a water molecule and C 60 in the endohedral fullerene H2O@C60. Physical Chemistry Chemical Physics, 21(6), 3347-3359. https://doi.org/10.1039/C8CP04390F

A water molecule encapsulated inside a C 60 fullerene cage behaves almost like an asymmetric top rotor, as would be expected of an isolated water molecule. However, inelastic neutron scattering (INS) experiments show evidence of interactions between... Read More about Interactions between a water molecule and C 60 in the endohedral fullerene H2O@C60.
