Pulse propagation in a medium with time-dependent refractive index — •Martin Kiffner1 and Tarak N. Dey1,2 — 1Max-Planck-Institut für Kernphysik, Saupfercheckweg 1, 69117 Heidelberg, Germany — 2Indian Institute of Technology Guwahati, Guwahati- 781 039, Assam, India
The phenomenon of electromagnetically induced transparency (EIT) gives rise to counterintuitive effects like the slowing and stopping of light and is of great importance, e.g., for the fields of quantum information theory and nonlinear optics [1]. Here we consider a standard EIT medium comprised of three-level Λ-type atoms and investigate the influence of a polychromatic control field on the propagation of the probe pulse. Our results are analyzed in terms of a time-dependent refractive index.
