Structural phase transitions of optical patterns in atomic gases with microwave-controlled Rydberg interactions (2020)
Journal Article
Shi, Z., Li, W., & Huang, G. (2020). Structural phase transitions of optical patterns in atomic gases with microwave-controlled Rydberg interactions. Physical Review A, 102(2), Article 023519. https://doi.org/10.1103/physreva.102.023519

Spontaneous symmetry breaking and formation of self-organized structures in nonlinear systems are intriguing and important phenomena in nature. Advancing such research to new nonlinear optical regimes is of much interest for both fundamental physics...

Hafele and Keating on a chip: Sagnac interferometry with a single clock (2020)
Presentation / Conference Contribution
Johnson, J., Foxon, B., Atkocius, V., Gentile, F., Jammi, S., Poulios, K., & Fernholz, T. Hafele and Keating on a chip: Sagnac interferometry with a single clock. Presented at Optical, Opto-Atomic, and Entanglement-Enhanced Precision Metrology II, San Francisco, United States

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.

Stable single light bullets and vortices and their active control in cold Rydberg gases (2019)
Journal Article
Bai, Z., Li, W., & Huang, G. (2019). Stable single light bullets and vortices and their active control in cold Rydberg gases. Optica, 6(3), 309-317. https://doi.org/10.1364/OPTICA.6.000309

Realizing single light bullets and vortices that are stable in high dimensions is a long-standing goal in the study of nonlinear optical physics. On the other hand, the storage and retrieval of such stable high dimensional optical pulses may offer a...
