EIT and AT: Two Similar but Distinct Phenomena in Two Categories of Three-Level Atomic Systems

Electromagnetically Induced Transparency (EIT) and Autler-Townes (AT) are two phenomena that could be featured by a variety of three-level atomic systems. The considered phenomena, EIT and AT, are similar "looking" in the sense that they both are characterized by a reduction in absorption of a weak field in the presence of a stronger field. In this paper, we explicitly set the threshold of separation between EIT and AT in a unified study of four different three-level atomic systems. Two resonances are studied and compared in each case. A comparison of the magnitudes of the resonances reveals two coupling field regimes and two categories of three-level systems.

Interference Between Competing Pathways in the Interaction of Three-Level Ladder Atoms and Radiation

In this paper we explore the physical origin of the transparency induced in absorbing three-level cascade atoms by the simultaneous interplay of two coherent beams of light. By utilizing the scattering technique we offer what we believe is a very convincing physical evidence for the existence, or for the absence, of quantum interference effects in the Autler-Townes (AT) and Electromagnetically Induced Transparency (EIT) phenomena.
