Self-Induced Transparency in Warm and Strongly Interacting Rydberg Gases (2020)
Journal Article
Bai, Z., Adams, C. S., Huang, G., & Li, W. (2020). Self-Induced Transparency in Warm and Strongly Interacting Rydberg Gases. Physical Review Letters, 125(26), Article 263605. https://doi.org/10.1103/PhysRevLett.125.263605

We study dispersive optical nonlinearities of short pulses propagating in high number density, warm atomic vapors where the laser resonantly excites atoms to Rydberg P states via a single-photon transition. Three different regimes of the light-atom i... Read More about Self-Induced Transparency in Warm and Strongly Interacting Rydberg Gases.
