The propagation of light in dispersive media is a subject of fundamental as well as practical
importance. In recent years attention has focused in particular on how refractive index can …

This paper reviews earlier studies on superluminal wave propagation in anomalously
dispersive media that have been carried out in the electronic, microwave, and optical …

We explain the probe field transmission spectrum under the influence of a strong pump field
in a hybrid optomechanical system, composed of an optical cavity, a mechanical resonator …

Recently a scheme has been proposed for detection of the structured light by measuring the
transmission of a vortex beam through a cloud of cold rubidium atoms with energy levels of …

Publisher Summary Atoms commonly do not act as isolated objects, but rather are open
quantum systems, as they interact with the environment. Typically, this environment is …

We introduce an operator linked with the radial index in the Laguerre-Gauss modes of a two-
dimensional harmonic oscillator in cylindrical coordinates. We discuss ladder operators for …

We were able to arbitrarily control the speed of a light pulse from subluminal to superluminal
velocity by changing only the power of the laser for coupling coherently the single transition …

We demonstrate tunable control of the group velocity of a weak probe pulse from subluminal
to superluminal. The model is an extended Λ-type system with two extra control fields and an …

We study the Fano resonance and slow light in a hybrid optomechanical system, where a
mechanical resonator is coupled to a cavity via radiation pressure and to a two-level system …
