Cooperative Atom-Light Interaction in a Blockaded Rydberg Ensemble (2010)
Journal Article
Pritchard, J., Maxwell, D., Gauguet, A., Weatherill, K., Jones, M., & Adams, C. (2010). Cooperative Atom-Light Interaction in a Blockaded Rydberg Ensemble. Physical Review Letters, 105(19), Article 193603. https://doi.org/10.1103/physrevlett.105.193603

By coupling a probe transition to a Rydberg state using electromagnetically induced transparency (EIT) we map the strong dipole-dipole interactions onto an optical field. We characterize the resulting cooperative optical nonlinearity as a function of... Read More about Cooperative Atom-Light Interaction in a Blockaded Rydberg Ensemble.

Two-Electron Excitation of an Interacting Cold Rydberg Gas (2010)
Journal Article
Millen, J., Lochead, G., & Jones, M. (2010). Two-Electron Excitation of an Interacting Cold Rydberg Gas. Physical Review Letters, 105(21), Article 213004. https://doi.org/10.1103/physrevlett.105.213004

We report the creation of an interacting cold Rydberg gas of strontium atoms. We show that the excitation spectrum of the inner valence electron is sensitive to the interactions in the Rydberg gas, even though they are mediated by the outer Rydberg e...

Rotational response of two-component Bose-Einstein condensates in ring traps (2010)
Journal Article
Halkyard, P., Jones, M., & Gardiner, S. (2010). Rotational response of two-component Bose-Einstein condensates in ring traps. Physical Review A, 81(6), Article 061602. https://doi.org/10.1103/physreva.81.061602

We consider a two-component Bose-Einstein condensate in a ring trap in a rotating frame and show how to determine the response of such a configuration to being in a rotating frame via accumulation of a Sagnac phase. This may be accomplished through e... Read More about Rotational response of two-component Bose-Einstein condensates in ring traps.

Modulation-free pump-probe spectroscopy of strontium atoms (2010)
Journal Article
Javaux, C., Hughes, I., Lochead, G., Millen, J., & Jones, M. (2010). Modulation-free pump-probe spectroscopy of strontium atoms. The European Physical Journal D, 57(2), 151-154. https://doi.org/10.1140/epjd/e2010-00029-4

We have performed polarization spectroscopy on the 5s21S0 →5s5p1P1 transition of atomic strontium. The signal is generated by saturation effects, rather than optical pumping, as the ground state is non-degenerate. This technique generated a dispersio...
