White-light versus discrete wavelength measurements of Faraday dispersion and the Verdet constant (2021)
Journal Article
Maxwell, J. L., Hughes, I. G., & Adams, C. S. (2022). White-light versus discrete wavelength measurements of Faraday dispersion and the Verdet constant. European Journal of Physics, 43(1), Article 015302. https://doi.org/10.1088/1361-6404/ac31d3

The wavelength dependence of the Faraday effect may be measured either sequentially at particular wavelengths using narrow band sources, or simultaneously at many wavelengths using a white-light or broadband source. We apply both methods to measure t... Read More about White-light versus discrete wavelength measurements of Faraday dispersion and the Verdet constant.

THz electrometry with Rydberg atoms and all IR lasers (2021)
Presentation / Conference Contribution
Chen, S., Reed, D., Downes, L. A., MacKellar, A. R., Almuhawish, N. F., Jamieson, M. J., Adams, C. S., & Weatherill, K. J. (2021, December). THz electrometry with Rydberg atoms and all IR lasers. Presented at 2021 46th International Conference on Infrared, Millimeter and Terahertz Waves (IRMMW-THz)

Rydberg electromagnetically induced transparency (EIT) and Autler-Townes (AT) splitting in an atomic vapor cell can be used as novel methods for electric-magnetic field detection. Here we make use of 3 infrared lasers to realize a Rydberg EIT system... Read More about THz electrometry with Rydberg atoms and all IR lasers.

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.

Collectively encoded Rydberg qubit (2021)
Journal Article
Spong, N. L., Jiao, Y., Hughes, O. D., Weatherill, K. J., Lesanovsky, I., & Adams, C. S. (2021). Collectively encoded Rydberg qubit. Physical Review Letters, 127(6), Article 063604. https://doi.org/10.1103/physrevlett.127.063604

We demonstrate a collectively-encoded qubit based on a single Rydberg excitation stored in an ensemble of N entangled atoms. Qubit rotations are performed by applying microwave fields that drive excitations between Rydberg states. Coherent read-out i... Read More about Collectively encoded Rydberg qubit.

Collective effects in the photon statistics of thermal atomic ensembles (2021)
Journal Article
Ribeiro, S., Cutler, T. F., Adams, C. S., & Gardiner, S. A. (2021). Collective effects in the photon statistics of thermal atomic ensembles. Physical Review A, 104(1), Article 013719. https://doi.org/10.1103/physreva.104.013719

We investigate the collective scattering of coherent light from a thermal alkali-metal vapor with temperatures ranging from 350 to 450 K, corresponding to average atomic spacings between 0.7 λ and 0.1 λ. We develop a theoretical model treating the at... Read More about Collective effects in the photon statistics of thermal atomic ensembles.

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-...
