Tunable homogeneous kG magnetic field production using permanent magnets (2021)
Journal Article
Pizzey, D. (2021). Tunable homogeneous kG magnetic field production using permanent magnets. Review of Scientific Instruments, 92(12), https://doi.org/10.1063/5.0064498

We present a permanent ring magnet arrangement that can achieve a tunable axial magnetic field from 1.80(5) to 2.67(9) kG. The apparatus has been designed to accommodate a cylindrical atomic vapor cell of length 25 mm and diameter 25 mm to lie within...

Rydberg excitons in synthetic cuprous oxide Cu2O (2021)
Journal Article
Lynch, S. A., Hodges, C., Mandal, S., Langbein, W., Singh, R. P., Gallagher, L. A., Pritchett, J. D., Pizzey, D., Rogers, J. P., Adams, C. S., & Jones, M. P. (2021). Rydberg excitons in synthetic cuprous oxide Cu2O. Physical Review Materials, 5(8), Article 084602. https://doi.org/10.1103/physrevmaterials.5.084602

High-lying Rydberg states of Mott-Wannier excitons are receiving considerable interest due to the possibility of adding long-range interactions to the physics of excitons. Here, we study Rydberg excitation in bulk synthetic cuprous oxide grown by the... Read More about Rydberg excitons in synthetic cuprous oxide Cu2O.

The Raspberry Pi auto-aligner: Machine learning for automated alignment of laser beams (2021)
Journal Article
Mathew, R. S., O’Donnell, R., Pizzey, D., & Hughes, I. G. (2021). The Raspberry Pi auto-aligner: Machine learning for automated alignment of laser beams. Review of Scientific Instruments, 92(1), Article 015117. https://doi.org/10.1063/5.0032588

We present a novel solution to automated beam alignment optimization. This device is based on a Raspberry Pi computer, stepper motors, commercial optomechanics and electronic devices, and the open-source machine learning algorithm M-LOOP. We provide...

Microwave-optical coupling via Rydberg excitons in cuprous oxide (2021)
Journal Article
Gallagher, L. A., Rogers, J. P., Pritchett, J. D., Mistry, R. A., Pizzey, D., Adams, C. S., Jones, M. P., Grünwald, P., Walther, V., Hodges, C., Langbein, W., & Lynch, S. A. (2022). Microwave-optical coupling via Rydberg excitons in cuprous oxide. Physical Review Research, 4(1), https://doi.org/10.1103/physrevresearch.4.013031

We report exciton-mediated coupling between microwave and optical fields in cuprous oxide (Cu2O) at low temperatures. Rydberg excitonic states with principal quantum number up to n = 12 were observed at 4 K using both one-photon (absorption) and two-...
