Coherent control of light-matter interactions in polarization standing waves
نویسندگان
چکیده
We experimentally demonstrate that standing waves formed by two coherent counter-propagating light waves can take a variety of forms, offering new approaches to the interrogation and control of polarization-sensitive light-matter interactions in ultrathin (subwavelength thickness) media. In contrast to familiar energy standing waves, polarization standing waves have constant electric and magnetic energy densities and a periodically varying polarization state along the wave axis. counterintuitively, anisotropic ultrathin (meta)materials can be made sensitive or insensitive to such polarization variations by adjusting their azimuthal angle.

Dynamical model of coherent circularly polarized optical pulse interactions with two-level quantum systems
We propose and develop a method for theoretical description of circularly elliptically polarized optical pulse resonant coherent interactions with two-level atoms. The method is based on the time-evolution equations of a two-level quantum system in the presence of a time-dependent dipole perturbation for electric dipole transitions between states with total angular-momentum projection differenc...
متن کاملLaser control of electron matter waves
In recent years laser light has been used to control the motion of electron waves. Electrons can now be diffracted by standing waves of light. Laser light in the vicinity of nanostructures is used to affect free electrons, for example, femto-second and atto-second laser-induced electrons are emitted from nanotips delivering coherent fast electron sources. Optical control of dispersion of the em...

We have built an optical magnetometer based on the nonlinear Faraday effect in hot Rb vapor and probe this device with both coherent light and polarization-squeezed light. We generate the squeezed light states using the polarization self-rotation effect in Rb vapor, optimized for the highest noise suppression, giving us a system which is allatomic. By probing with polarization-squeezed states o...

Second-order nonlinear optical diffraction by standing acoustic waves in a crystalline plate is theoretically investigated. A detailed analysis of the polarization state of the second-harmonic light diffracted by both longitudinal and transversal acoustic waves is carried out. It is shown that longitudinal standing acoustic waves only allow p-polarized nonlinear optical diffraction, irrespectiv...
متن کاملAnti-Matter Wave Interferometry with Positronium
Atomic matter wave optics is a well-developed field in physics. Many different coherent manipulation techniques for atoms have been developed. In this paper the application of one of these techniques, Bragg scattering at near-resonant standing light waves, for ortho-Positronium is discussed. Utilizing Bragg diffraction as a coherent splitting mechanism the realization of a Positronium interfero...
