Rapid readout of terahertz orbital angular momentum beams using atom-based imaging (2022)
Journal Article
Downes, L. A., Whiting, D. J., Adams, C. S., & Weatherill, K. J. (2022). Rapid readout of terahertz orbital angular momentum beams using atom-based imaging. Optics Letters, 47(22), 6001-6004. https://doi.org/10.1364/ol.476945

We demonstrate the rapid readout of terahertz orbital angular momentum (OAM) beams using an atomic-vapor-based imaging technique. OAM modes with both azimuthal and radial indices are created using phase-only transmission plates. The beams undergo ter...

Purcell-enhanced dipolar interactions in nanostructures (2022)
Journal Article
Skljarow, A., Kübler, H., Adams, C., Pfau, T., Löw, R., & Alaeian, H. (2022). Purcell-enhanced dipolar interactions in nanostructures. Physical Review Research, 4(2), https://doi.org/10.1103/physrevresearch.4.023073

Strong light-induced interactions between atoms are known to cause nonlinearities at a few-photon level, which are crucial for applications in quantum information processing. Compared to free space, the scattering and the light-induced dipolar intera... Read More about Purcell-enhanced dipolar interactions in nanostructures.

Terahertz electrometry via infrared spectroscopy of atomic vapor (2022)
Journal Article
Chen, S., Reed, D. J., MacKellar, A. R., Downes, L. A., Almuhawish, N. F., Jamieson, M. J., Adams, C. S., & Weatherill, K. J. (2022). Terahertz electrometry via infrared spectroscopy of atomic vapor. Optica, 9(5), 485-491. https://doi.org/10.1364/optica.456761

In recent years, the characterisation of radiation falling within the so-called ‘terahertz (THz) gap’ has become an ever more prominent issue due to the increasing use of THz systems in applications such as nondestructive testing, security screening,...

Transient Density-Induced Dipolar Interactions in a Thin Vapor Cell (2022)
Journal Article
Christaller, F., Mäusezahl, M., Moumtsilis, F., Belz, A., Kübler, H., Alaeian, H., Adams, C. S., Löw, R., & Pfau, T. (2022). Transient Density-Induced Dipolar Interactions in a Thin Vapor Cell. Physical Review Letters, 128(17), Article 173401. https://doi.org/10.1103/physrevlett.128.173401

We exploit the effect of light-induced atomic desorption to produce high atomic densities (n ≫ k3) in a rubidium vapor cell. An intense off-resonant laser is pulsed for roughly one nanosecond on a micrometersized sapphire-coated cell, which results i...

High-resolution nanosecond spectroscopy of even-parity Rydberg excitons in Cu2O (2022)
Journal Article
Rogers, J. P., Gallagher, L. A., Pizzey, D., Pritchett, J. D., Adams, C. S., Jones, M. P., Hodges, C., Langbein, W., & Lynch, S. A. (2022). High-resolution nanosecond spectroscopy of even-parity Rydberg excitons in Cu2O. Physical Review B, 105(11), Article 115206. https://doi.org/10.1103/physrevb.105.115206

We present a study of even-parity Rydberg exciton states in cuprous oxide using second harmonic generation (SHG) spectroscopy. Excitonic states with principal quantum number n = 5 − 12 were excited by nanosecond pulses around 1143 nm. Using time-reso...
