Sub- and super-luminal light propagation using a Rydberg state

TL;DR: In this paper, a theoretical analysis of sub-and super-luminal light propagation in a rubidium atomic system consisting of a Rydberg state by using density matrix formalism is performed in a 4-level vee+ladder system interacting with a weak probe and strong control and switching fields.
Journal ArticleDOI

Electromagnetic induced transparency in the Doppler broadened cascade transition with multiple excited levels

TL;DR: In this paper, a theoretical model using the density matrix approach has been presented to show the influence of multiple excited states on electromagnetically induced transparency (EIT) in a cascade-type Doppler broadened medium.
Journal ArticleDOI

Role of dressed-state interference in electromagnetically induced transparency

TL;DR: In this article, the role of dressed-state interference in causing EIT in three-level systems was investigated, and it was shown that dressed state interference caused probe absorption to go to zero in a Λ system, but played a negligible role in Ξ and V systems.
Journal ArticleDOI

Coherent population trapping (CPT) versus electromagnetically induced transparency (EIT)

TL;DR: In this paper, the authors discuss the differences between coherent population trapping (CPT) and electromagnetically induced transparency (EIT) and demonstrate experimentally the effect of power in the beams, detuning of the beams from resonance, and the use of vapor cells filled with buffer gas.
Journal ArticleDOI

Study of EIT resonances in an anti-relaxation coated Rb vapor cell

TL;DR: In this article, the sign of magnetic sublevels of a hyperfine transition in the D-1 line of Rb-87 along with a magnetic field of 27 G was studied.
