Cosmic Shear and the Intrinsic Alignment of Galaxies
(2010-11-12)
Cosmology has recently entered an era of increasingly rich observational data sets, all being in agreement with a cosmological standard model that features only a small number of free parameters. One of the most powerful ...
State-selective transport of single neutral atoms
(2010-11-05)
The present work investigates the state-selective transport of single neutral cesium atoms in a one-dimensional optical lattice. It demonstrates experimental applications of this transport, including a single atom ...
Datengetriebenes Clustering funktionell tomographischer Daten
(2011-02-24)
In der vorliegenden Arbeit wurden mit Hilfe eines datengetriebenen Verfahrens dynamische Eigenschaften von Daten der funktionellen Magnetresonanztomographie (fMRT) mit dem Ziel analysiert, neuronale Aktivität auf der Basis ...
Bose-Einstein-Kondensation von paraxialem Licht
(2011-03-02)
Einer der faszinierenden Aspekte der Bose-Einstein-Kondensation ist, dass sie selbst in idealen, d.h. wechselwirkungsfreien, Bose-Gasen auftritt, wodurch sie sich grundlegend von allen Phasenübergängen unterscheidet, bei ...
Embedding the DFSZ–Axino in mSUGRA with R–Parity Violation and its implications for Dark Matter
(2011-01-21)
We embed the DFSZ axion in supersymmetry with broken R–parity. As Supersymmetry provides hundreds of free parameters we restrict ourselves to the lepton–number violating scenario in minimal supergravity models with ...
Microscopic Theory of Random Lasing and Light Transport in Amplifying Disordered Media
(2011-03-10)
In the last decade Anderson Localization of Light and Random Lasing has attracted a variety of interest in the community of condensed matter theory. The fact that a system so inartificial as a thin layer consisting of dust ...
The Fluctuating Gap Model
(2011-02-10)
The quasi-one-dimensional systems exhibit some unusual phenomenon, such as the Peierls instability, the pseudogap phenomena and the absence of a Fermi-Dirac distribution function line shape in the photoemission spectroscopy. ...
Measurement of beam asymmetries in the reaction γp→pπ<sup>0</sup>η with the Crystal Barrel/TAPS experiment at ELSA
(2011-01-06)
The photoproduction of mesons off the nucleon provides an excellent tool to gain further insight into the structure of baryons and their excitation spectrum. A large number of final states yielding various resonance ...
Entwicklung und Validierung eines Ausbreitungsmodells für Aerosole und Untersuchungen zu deren Koagulation als potentieller Einflußquelle
(2010-09-10)
Das vorliegende Promotionsprojekt baut auf einem in einer gemeinsamen Arbeitsgruppe von Physikalischem Institut und Institut für Landtechnik neu entwickelten dynamischen Modell auf Basis der Lösung der Navier-Stokes-Gleichungen ...
Measurement of beauty and charm photoproduction using inclusive secondary vertexing with the ZEUS detector at HERA
(2010-05-06)
Photoproduction of heavy quarks in events with two jets has been measured with the ZEUS detector at HERA using data recorded in the years 2006-2007 corresponding to an integrated luminosity of 128 pb<sup>-1</sup>. The ...
