Optical coherences and wavelength mismatch in ladder systems
A. Urvoy, C. Carr, R. Ritter +3
We investigate experimentally and theoretically the coherent and incoherent processes in open 3-level ladder systems in room temperature gases and identify in which regime electrom…

Cooperative non-equilibrium phase transition in a dilute Rydberg ensemble
Christopher Carr, Ralf Ritter, Christopher Wade +2
We demonstrate a non-equilibrium phase transition in a dilute thermal atomic gas. The phase transition, between states of low and high Rydberg occupancy, is induced by resonant dip…
