Comment on "Electromagnetically induced left handedness in optically excited four-level atomic media".
In a recent paper (Phys. Rev. Lett. 96, 053601 (2006)) Thommen and Mandel discussed a novel scheme to induce left-handedness and negative refraction in an atomic four-level scheme [1]. The proposal is based on a coherent cross-coupling between electric and magnetic dipole transitions, which couple to the electric and magnetic field components of the probe field. A very important feature of the ...
متن کاملElectromagnetically induced left handedness in optically excited four-level atomic media.
We show that left-handed properties can be electromagnetically induced in a general four-level atomic medium for a finite spectral range. We use an electric (magnetic) atomic transition as an electric (magnetic) resonator to modify the permittivity (permeability), both at the same frequency. The implementation of the four-level model is carried out in atomic hydrogen and neon. In each case the ...
متن کاملElectromagnetically induced transparency and its dispersion properties in a four-level inverted-Y atomic system
We consider a four-level atomic system in inverted-Y configuration and study the phenomenon of electromagnetically induced transparency (EIT) in this system under various parametric conditions in order to demonstrate controllability of the EIT and its dispersion properties. 2003 Elsevier B.V.

متن کاملSlow light propagation and amplification via electromagnetically induced transparency and four-wave mixing in an optically dense atomic vapor
We experimentally and theoretically analyze the propagation of weak-signal field pulses under the conditions of electromagnetically induced transparency (EIT) in hot Rb vapor, and study the effects of resonant four-wave mixing (FWM). In particular, we demonstrate that in a doublesystem, formed by the strong control field with the weak resonant signal and a far-detuned Stokes field, both continu...
متن کاملLight storage in an optically thick atomic ensemble under conditions of electromagnetically induced transparency and four-wave mixing
We study the modification of a traditional electromagnetically induced transparency (EIT) stored-light technique that includes both EIT and four-wave mixing (FWM) in an ensemble of hot Rb atoms. The standard treatment of light storage involves the coherent and reversible mapping of one photonic mode onto a collective spin coherence. It has been shown that unwanted, competing processes such as f...
