Phase-space views into dye-microcavity thermalized and condensed photons

Collapses and revivals of exciton emission in a semiconductor microcavity: detuning and phase-space filling effects

We investigate exciton emission of quantum well embedded in a semiconductor microcavity. The analytical expressions of the light intensity for the cases of excitonic number state and coherent state are presented by using secular approximation. Our results show that the effective exciton-exciton interaction leads to the appearance of collapse and revival of the light intensity. The revival time ...

InSAR Phase Unwrapping by Transforming Sparce Data into a Regular Space

Phase unwrapping is one of the most important parts of InSAR techniques. In order to estimate the grand surface displacements, interferomtric phases modulated between 0 to 2π must be unwrapped. Based on the use of either the conventional method or persistent scatterer (PS), phases will be spread both regularly and irregularly. The phases of PSs can be unwrapped by reducing phases into a regular...

Synchrotron Phase Space Injection Into LEP

Although LEP was designed to allow both betatron and synchrotron injection, only betatron accumulation has been used up to now. During 1994 tests were made of injection in synchrotron phase space. Results are presented from these machine studies which show that for both 4 bunch and 8 bunch pretzel injection, this form of injection is a more efficient way of accumulating LEP beams. The use of sy...

Neutralino Annihilation into Two Photons

We compute the annihilation cross-section of two neutralinos at rest into two photons, which is of importance for the indirect detection of neutralino dark matter in the galactic halo through a quasi-monochromatic gamma-ray line. We include all diagrams to one-loop level in the minimal supersymmetric extension of the standard model. We use the helicity formalism, the backgroundfield gauge, and ...
