The propagation of polarized photons in optical media can be effectively modeled by means of quantum dynamical semigroups. These generalized time evolutions consistently describe phenomena leading to loss of phase coherence and dissipation originating from the interaction with a large, external environment. High sensitive experiments in the laboratory can provide stringent bounds on the fundame...

We searched the 9 M-dwarf primaries nearer than 5 pc and south of declination δ = −30◦ for companions with separations 1-10AU and found none. Taken togetherwith the 25 northern primaries studied by Henry and McCarthy (1990) the fraction of binaries and triples within the now complete sample of all M dwarfs within 5 pc is 9/34 = 26± 9%, and the average number of companions per system is 0.32± 0....

The phase perturbation arising from spin-rotation coupling is developed as a natural extension of the celebrated Sagnac effect. Experimental evidence in support of this phase shift, however, has yet to be realized due to the exceptional sensitivity required. We draw attention to the relevance of a series of experiments establishing that circularly polarized light, upon passing through a rotatin...

The potential of differential SAR interferometry for land subsidence monitoring is reported on. The principle of the technique and the approach to be used on a specific case are first presented. Then significant results using SAR data from the ERS satellites for various sites in Germany, Mexico, and Italy, representing fast (mlyear) to slow (mmlyear) deformation velocities, are discussed. The S...

Over the past 6 years we have conducted an extensive monitoring program of Io at near infrared wavelengths, in order to determine the location, frequency, and duration of the volcanic activity on this satellite of Jupiter. The observations were obtained at the Wyoming 2.3-m telescope using a near-infrared speckle interferometry system that provides standard photometry and in addition can locate...

Andreev interferometry—the sensitivity of the tunneling current to spatial variations in the local superconducting order at an interface—is proposed as a probe of the spatial structure of the phase correlations in the pseudogap state of the cuprate superconductors. To demonstrate this idea theoretically, a simple tunneling model is considered, via which the tunneling current is related to the e...

Silver metal trees grow and form a forest at the edge of a Cu plate in the AgNO3 water solution in a two dimensional(d = 2) cell. The local structure of the forest is similar to that of the diffusion-limited aggregation (DLA), but the whole pattern approaches a uniform structure. Its growth dynamics is characterized by the fractal dimension Df of DLA. Time-dependence of the tip height is found ...

This lecture is mainly based on the work of S.R. Cloude and presents examples for remote sensing applications Polarimetric SAR Interferometry (PolInSAR). PolInSAR has its origins in remote sensing and was first developed for applications in 1997 using SIRC L-Band data [1,2]. In its original form it involved generating phase differences between interferograms formed using different polarization ...
