Anisotropic weak localization of light.

چکیده
We have observed angular anisotropy in weak localization of light from highly scattering, orientationally ordered, nematic liquid crystals. This demonstration of angular anisotropy in a multiple-scattering interference phenomenon was facilitated by a light scattering instrument with extraordinary angular resolution. The measured anisotropies were consistent with a simple model of coherent backscattering generalized for propagation-direction dependent mean free paths.

Eigenstates of the Atom-Field Interaction and the Binding of Light in Photonic Crystals
We solve for the exact atom-field eigenstates of a single atom in a three dimensional spherical cavity, by mapping the problem onto the anisotropic Kondo model. The spectrum has a rich bound state structure in comparison with models where the rotating wave approximation is made. It is shown how to obtain the Jaynes-Cummings model states in the limit of weak coupling. Non-perturbative Lamb shift...
متن کاملQuantum transport of atomic matter waves in anisotropic two-dimensional and three-dimensional disorder
The macroscopic transport properties in a disordered potential, namely diffusion and weak/strong localization, closely depend on the microscopic and statistical properties of the disorder itself. This dependence is rich in counter-intuitive consequences. It can be particularly exploited in matter wave experiments, where the disordered potential can be tailored and controlled, and anisotropies a...

متن کاملCoherent Optics and Localized Light
Interplay between the effects of coherent radiation and localization of light is analysed. A system of two–level atoms is placed in a medium interacting with electromagnetic field. The matter–light interaction can result in the appearance of a band gap in the spectrum of polariton states. If an atom with a resonance frequency inside the gap is incorporated into such a medium, the atomic spontan...
متن کاملAnisotropic L−estimates of weak solutions to the stationary Oseen-type equations in 3D-exterior domain for a rotating body S.Kra£mar, .Ne£asová and P.Penel
We study the Oseen problem with rotational e ect in exterior three-dimensional domains. Using a variational approach we prove existence and uniqueness theorems in anisotropically weighted Sobolev spaces in the whole three-dimensional space. As the main tool we derive and apply an inequality of the FriedrichsPoincaré type and the theory of Calderon-Zygmund kernels in weighted spaces. For the ext...
