In this theoretical–experimental study, we use the Fresnel–Kirchhoff diffraction theory to simulate formation of far-field pattern a divergent Gaussian beam propagated through photorefractive crystal Bi 12 GeO 20 (BGO). We show that for BGO, in addition wavefront curvature and change refractive index medium due light intensity, there is third contribution affecting medium-induced nonlinear phas...
We consider interference patterns produced by coherent arrays of Bose-Einstein condensates during their one-dimensional expansion. Several characteristic pattern structures are distinguished depending on value of the evolution time. Transformation of Talbot “collapse-revival” behavior to Fraunhofer interference fringes is studied in detail.

We fabricate superconductor–graphene– superconductor Josephson junctions with superconducting regions made of lead (Pb). The critical current through graphene may be modulated by the external magnetic field; the resulting Fraunhofer interference pattern shows several periods of oscillations, suggesting that the junction is uniform. Deviations from the perfect Fraunhofer pattern are observed, an...

Annotation of digital recordings in humanities research still is, to a large extend, a process that is performed manually. This paper describes the first pattern recognition based software components developed in the AVATecH project and their integration in the annotation tool ELAN. AVATecH (Advancing Video/Audio Technology in Humanities Research) is a project that involves two Max Planck Insti...
