Pair production of Higgs bosons in the final state with bottom quarks and τ leptons in the ATLAS experiment: Search results using LHC Run 2 data and prospect studies at the HL-LHC
(2021-03-30)After the discovery of the Higgs boson, the ultimate test of the electroweak symmetry breaking and the Standard Model (SM) of particle physics is to establish evidence of Higgs boson self-coupling, which can be achieved ... -
Parallele Datenakquisition zur Beschleunigung Diffusionsgewichteter Kernspintomographie mit Stimulierten Echos
(2007-04-18)Magnetic resonance imaging (MRI) experiments can be sensitised to the erratic thermal displacement of (water) molecules by the application of magnetic field gradients. The associated signal ... -
Parameterschätzung und Modellevaluation für komplexe Systeme
(2016-10-17)Mathematical models in form of dynamical systems play an important role in many disciplines, such as system biology, engineering, or physics. They are widely used to simulate the time evolution of the internal states of ... -
Parametric Bose-Hubbard Hamiltonians: Quantum Dissipation, Irreversibility, and Pumping
(2008-09-11)In this thesis, we study interacting bosons on lattices consisting of a few sites. The main focus is on their response to external driving fields, their transport and decay properties. We ... -
Particle - Tracking - Velocimetry - Messungen an kollabierenden Kavitationsblasen
(2008-12-01)The flowfields around cavitation bubbles collapsing near obstacles are investigated in this work. For this purpose, photographs of the laser-induced bubbles are taken and the method of ... -
Partikelmodellierung der Strukturbildung akustischer Kavitationsblasen in Wechselwirkung mit dem Schalldruckfeld
(2006-10-10)When a strong acoustic field is coupled into a liquid, it ruptures and bubbles emerge (acoustic cavitation). The acoustic cavitation bubbles show volume oscillations as well as a translative ... -
Pattern Formation in Membranes with Quenched Disorder
(2015-01-23)The lateral heterogeneity in the plasma membrane of eukaryotic cells is an important factor for regulating biological functions. As opposed to plasma membranes, model membranes (either artificially prepared membranes, or ... -
Pattern Formation in Spatially Forced Thermal Convection
(2010-02-04)In this work experimental results on forced thermal convection are presented. Experiments were done in a large aspect ratio cell slightly above the critical temperature difference at which ... -
Pattern selection in the visual cortex
(2006-04-25)The orientation map in the primary visual cortex is an important model system for studying cortical development. By quantifying large sets of functional brain imaging data we find that the ... -
Phase Behavior of Liquid Crystals in Confinement
(2012-01-12)We use computer simulations to investigate the isotropic-to-nematic phase transition of liquid crystals. Using the Lebwohl-Lasher model with sophisticated algorithms, the phase transition ... -
Phase behaviour of random copolymers and crosslinked homopolymer blends
(2005-11-25)The phase behaviour of molten linear random block copolymers and of randomly crosslinked homopolymer blends is studied in the framework of statistical mechanics based on microscopic models.In ... -
Phase diagrams of two-dimensional frustrated spin systems
(2012-04-19)In this work the ordering processes in classical frustrated Ising models and the ground-state behavior of frustrated quantum spin models are investigated. In the first part the phase transition from a high-temperature ... -
Phase formation processes in the synthesis of boron nitride thin films
(2005-11-02)As a diamond-like material, cubic boron nitride (c-BN) exhibits extraordinary mechanical, electrical, chemical, and thermal properties, making it a promising material for corrosion- and ... -
Phase retrieval for object and probe in the optical near-field
(2016-01-12)Lensless, holographic X-ray microscopy is a non-invasive imaging technique that provides resolution on the nanometer scale. Therefore, a divergent, coherent and especially clean wavefront impinging on the sample is needed. ... -
Phase-Dependent Energy Dissipation Processes in La0.7Sr0.3MnO3 and (La0.6Pr0.4)0.7Ca0.3MnO3 after an Ultrashort Optical Excitation
(2023-08-31)La0.7Sr0.3MnO3 (LSMO) and (La0.6Pr0.4)0.7Ca0.3MnO3 (LPCMO) are perovsikte manganites which both show a ferromagnetic-to-paramagnetic phase transition. Interestingly, the development of the new phase when crossing the ... -
Phasenaufgelöste Spektrophotometrie des magnetischen kataklysmischen Veränderlichen EX Hya
(2001-01-03)This thesis describes time-resolved observations of the eclipsing intermediate polar (IP) EX Hya at X-ray, UV, optical and near infrared wavelengths. IPs form a subclass of the cataclysmic ... -
Phasenbildung, Phasenübergang und mechanische Eigenschaften des Funktionsmaterials Eisen-Palladium
(2010-09-03)The alloy Iron-Palladium is a smart material whose properties can be strongly influenced in several ways. If the Palladium content is about 30%, the material undergoes a martensitic ... -
Phenomenology at a future 100 TeV hadron collider
(2018-03-13)Run 1 of the Large Hadron Collider (LHC) has been one of the most successful experiments in particle physics. We are now approaching the end of LHC Run 2, and whether we will discover new physics or not, the high ... -
Photo-magnonics in two-dimensional antidot lattices
