Correlated photon pairs generated from a warm atomic ensemble
R. T. Willis, F. E. Becerra, L. A. Orozco +1
We present measurements of the cross-correlation function of photon pairs at 780 nm and 1367 nm, generated in a hot rubidium vapor cell. The temporal character of the biphoton is d…
Non-degenerate four-wave mixing in rubidium vapor: transient regime
F. E. Becerra, R. T. Willis, S. L. Rolston +2
We investigate the transient response of the generated light from Four-Wave Mixing (FWM) in the diamond configuration using a step-down field excitation. The transients show fast d…
Interactions Between Rydberg-Dressed Atoms
J. E. Johnson, S. L. Rolston
We examine interactions between atoms continuously and coherently driven between the ground state and a Rydberg state, producing "Rydberg-dressed atoms." Because of the large dipol…
Electron Evaporation from an Ultracold Plasma in a Uniform Electric Field
K. A. Twedt, S. L. Rolston
Electrons in an expanding ultracold plasma are expected to be in quasi-equilibrium, since the collision times are short compared to the plasma lifetime, yet we observe electrons ev…
