Maximal refraction and superluminal propagation in a gaseous nanolayer
J. Keaveney, I. G. Hughes, A. Sargsyan +2
We present an experimental measurement of the refractive index of high density Rb vapor in a gaseous atomic nanolayer. We use heterodyne interferometry to measure the relative phas…
N -resonances in a buffered micrometric Rb cell: splitting in a strong magnetic field
Armen Sargsyan, Rafayel Mirzoyan, Aram Papoyan +1
N -resonances excited in rubidium atoms confined in micrometric-thin cells with variable thickness from 1 μm to 2 mm are studied experimentally for the cases of a pure Rb atomic va…
Three-photon electromagnetically induced transparency using Rydberg states
Christopher Carr, Monsit Tanasittikosol, Armen Sargsyan +3
We demonstrate electromagnetically induced transparency (EIT) in a four-level cascade system where the upper level is a Rydberg state. The observed spectral features are sub-Dopple…
The cooperative Lamb shift in an atomic nanolayer
James Keaveney, Armen Sargsyan, Ulrich Krohn +3
We present an experimental measurement of the cooperative Lamb shift and the Lorentz shift using an atomic nanolayer with tunable thickness and atomic density. The cooperative Lamb…
