ARC: An open-source library for calculating properties of alkali Rydberg atoms (2017)
Journal Article
Šibalić, N., Pritchard, J. D., Adams, C. S., & Weatherill, K. J. (2017). ARC: An open-source library for calculating properties of alkali Rydberg atoms. Computer Physics Communications, 220, 319-331. https://doi.org/10.1016/j.cpc.2017.06.015

We present an object-oriented Python library for computation of properties of highly-excited Rydberg states of alkali atoms. These include single-body effects such as dipole matrix elements, excited-state lifetimes (radiative and black-body limited)...

Single-photon interference due to motion in an atomic collective excitation (2017)
Journal Article
Whiting, D. J., Šibalić, N., Keaveney, J., Adams, C. S., & Hughes, I. G. (2017). Single-photon interference due to motion in an atomic collective excitation. Physical Review Letters, 118(25), Article 253601. https://doi.org/10.1103/physrevlett.118.253601

We experimentally demonstrate the generation of heralded bi-chromatic single photons from an atomic collective spin excitation (CSE). The photon arrival times display collective quantum beats, a novel interference effect resulting from the relative m...

Real-Time Near-Field Terahertz Imaging with Atomic Optical Fluorescence (2016)
Journal Article
Wade, C., Šibalić, N., De Melo, N., Kondo, J., Adams, C., & Weatherill, K. (2017). Real-Time Near-Field Terahertz Imaging with Atomic Optical Fluorescence. Nature Photonics, 11(1), 40-43. https://doi.org/10.1038/nphoton.2016.214

Terahertz (THz) near-field imaging is a flourishing discipline, with applications from fundamental studies of beam propagation to the characterization of metamaterials, and waveguides. Beating the diffraction limit typically involves rastering struct... Read More about Real-Time Near-Field Terahertz Imaging with Atomic Optical Fluorescence.

Dressed-state electromagnetically induced transparency for light storage in uniform-phase spin waves (2016)
Journal Article

We present, experimentally and theoretically, a scheme for dressed-state electromagnetically induced transparency (EIT) in a three-step cascade system in which a four-level system is mapped into an effective three-level system. Theoretical analysis r... Read More about Dressed-state electromagnetically induced transparency for light storage in uniform-phase spin waves.

Driven-dissipative many-body systems with mixed power-law interactions: Bistabilities and temperature-driven nonequilibrium phase transitions (2016)
Journal Article

We investigate the nonequilibrium dynamics of a driven-dissipative spin ensemble with competing power-law interactions. We demonstrate that dynamical phase transitions as well as bistabilities can emerge for asymptotic van der Waals interactions, but...

Intrinsic Optical Bistability in a Strongly-Driven Rydberg Ensemble (2016)
Journal Article

We observe and characterize intrinsic optical bistability in a dilute Rydberg vapor. The bistability is characterized by sharp jumps between states of low and high Rydberg occupancy with jump-up and -down positions displaying hysteresis depending on...

We report on the observation of electromagnetically induced transparency (EIT) and absorption (EIA) of highly excited Rydberg states in thermal Cs vapor using a four-step excitation scheme. The advantage of this four-step scheme is that the final tra...
