Landau-Zener-Stückelberg Interferometrie mit ultrakalten Atomen in Fouriersynthetisierten optischen Gitterpotentialen
(2011-12-12)
In dieser Arbeit werden Experimente zur Konstruktion eines Zweistrahl-Atominterferometers beschrieben. Für die Experimente wurde ein atomares Bose-Einstein Kondensat hergestellt und mit einem variablen bichromatischen ...
Single molecule tracking with light sheet microscopy
(2011-11-11)
The work presented here concentrates on light sheet based fluorescence microscopy (LSFM) and its application to single molecule tracking.
In LSFM the sample is illuminated perpendicular to the detection axis with a ...

Mobilität endogener mRNA im chromatinfreien Nukleoplasma der Speicheldrüsenzellkerne von Chironomus tentans
(2011-07-26)
In eukaryotischen Zellen ist fast die gesamte genetische Information in Form chromosomaler DNA im Zellkern gespeichert, während die molekulare Maschinerie zur Translation ausschließlich cytoplasmatisch lokalisiert ist. Der ...
Study of top-quark pair cross-section measurement in the dilepton channel with the ATLAS detector at the LHC
(2011-09-16)
The top quark is the heaviest of the known fundamental particles in the Standard Model (SM) with a mass of 173.3±1.1GeV. It is the sixth quark in the SM and the weak isospin partner of the bottom quark. Properties such as ......
Studies into tau reconstruction, missing transverse energy and photon induced processes with the ATLAS detector at the LHC
(2011-10-11)
The ATLAS experiment is currently recording data from proton-proton collisions delivered by CERN's Large Hadron Collider. As more data is amassed, studies of both Standard Model processes and searches for new physics beyond ......
Topological string theory, modularity and non-perturbative physics
(2011-09-28)
In this thesis the holomorphic anomaly of correlators in topological string theory, matrix models and supersymmetric gauge theories is investigated. In the first part it is shown how the techniques of direct integration ...
Computational Simulation of Trabecular Bone Distribution around Dental Implants and the Influence of Abutment Design on the Bone Reaction for Implant-Supported Fixed Prosthesis
(2011-09-30)
Computational modelling of trabecular bone distribution based on the remodelling process is a challenging issue. Up to now, most of bone remodelling models attempted to describe the remodelling process with noncemented ...
Search for Supersymmetry and kinematic endpoint measurement in final states with two tau leptons with the ATLAS detector at the LHC
(2011-10-21)
Discovery prospects for Supersymmetry in final states with at least two tau leptons and large missing transverse energy are evaluated for LHC proton-proton collisions measured with the ATLAS detector. In a first study based ......
Das Entdeckungspotential von Supersymmetrie mit Endzust¨anden aus mindesten zwei Tau Leptonen und fehlender Transversalenergie in Proton-Proton Kollisionen wird untersucht, sowie die M¨oglichkeit einer Messung des Endpunktes ......

Searching for High-energy Neutrinos from Supernovae with IceCube and an Optical Follow-up Program
(2011-10-21)
In violent astrophysical processes high-energy neutrinos of TeV to PeV energies are expected to be produced along with the highest energy cosmic rays. The acceleration of nuclei to very high energies is assumed to takes ...
Few-Body Physics in Quantum Gases
(2011-10-25)
Few-body effects play an important role for the understanding of ultracold quantum gases. We make use of an effective field theory approach to investigate various aspects of universal few-body physics close to a Feshbach ...
