Observation of the Standard Model Higgs boson produced in association with a pair of top quarks at $\sqrt{s} = 13 \, \text{TeV}$ with the ATLAS experiment at the LHC with emphasis on the decay of the Higgs boson into a $b\bar{b}$-pair in the single-lepton channel
(2019-10-30)The top quark is the heaviest elementary particle in the Standard Model and has an expected Yukawa coupling to the Higgs boson of order unity. The value of this coupling is a key ingredient to unravel the nature of the ... -
Observationally driven 3D MHD model of the solar corona above a magnetically active region
(2014-07-15)Context: The corona of the Sun can be observed since 1932 with instruments occulting the solar disc. Only few years later it became clear that the corona is way hotter than the visible solar surface and since then, the ... -
Observations and modeling of polar faculae on the Sun
(2004-12-21)In this work the structure and dynamics of polar faculae on the Sun, which constitute an important part of the magnetic solar cycle, were studied by means of high resolution spectropolarimetric ... -
Observations of large-scale solar flows
(2021-04-13)In this dissertation, several components of large-scale solar flows are studied observationally: solar equatorial Rossby waves (waves of radial vorticity), large-scale convection, and surface flows around active regions. ... -
On Infravacua and the Superselection Structure of Theories with Massless Particles
(2001-08-07)In quantum field theories with massless particles, states carrying a nontrivial superselection charge may have very poor localisation properties when compared to the vacuum. In this case, ... -
On Soret Convection in Binary and Pseudo-Binary Liquid Mixtures
(2008-05-20)Soret convection in binary ethanol-water mixtures and a pseudo-binary microemulsion is experimentally investigated by means of velocity amplitude measurements and flow field visualisation. The results for the molecular ... -
On the Construction of Quantum Field Theories with Factorizing S-Matrices
(2006-10-25)The subject of this thesis is a novel construction method for interacting relativistic quantum field theories on two-dimensional Minkowski space. Employing the algebraic framework of quantum ... -
On the Detection of Exomoons in Photometric Time Series
(2019-09-02)One of the next big steps forward for exoplanet science would be the detection of moons around extrasolar planets. In this thesis I investigate the exomoon candidate around the exoplanet Kepler-1625 b. I estimate the ... -
On the evolution and simulation of strange-mode instabilities
(2003-09-17)Sufficiently luminous objects, such as massive stars, suffer from strange mode instabilities with growth rates in the dynamical range. The boundary of the domain in the Hertzsprung-Russel ... -
On the Formation and Evolution of Dwarf Galaxies in Tidal Tails
(2002-12-04)Tidal Dwarf Galaxies (TDGs) are a class of dwarf galaxies that form in tidal tails of interacting giant galaxies during close encounters or merging. As such they offer the possibility of ... -
On the interplanetary properties and evolution of CME-driven shocks
(2017-05-10)This work presents the analysis of eleven CME events which were observed by instruments of the Sun-Earth Connection Coronal and Heliospheric Investigation (SECCHI) imaging suite on board the NASA Solar TErrestrial RElations ... -
On the mechanics of biopolymer networks
(2016-06-07)In this thesis, we study the mechanical properties of biopolymer networks. We discuss which of these properties can be described by continuum approaches and which features, on the contrary, require consideration of the ... -
On the stability of massive stars
(2017-01-16)On the basis of the equations for stellar structure together with an equation of state, stellar models may be constructed. Using these stellar models, the effects of different parameters on the evolution and internal ... -
Open Mesoscopic Systems: beyond the Random Matrix Theory
(2003-08-19)Physical systems having sizes between microscopic and macroscopic are referred to as mesoscopic. The motion in mesoscopic systems is phase-coherent, that means they must be treated ... -
Optical and Near Infrared studies of the photometric structure and starburst activity of Blue Compact Dwarf Galaxies
(2003-06-30)This thesis describes three studies of Blue Compact Dwarf Galaxies (BCDs), focussed on the structure of the stellar components, the star-forming activity, and the environment of such galaxies, ... -
Optical Excitation in Scanning Tunneling Microscopy: From Surface Photovoltages to Charge Dynamics oin the Atomic Scale
(2017-05-04)In this thesis, the successful implementation of optical excitation for time-resolved Scanning Tunneling Microscopy (STM) is presented. The fruitful combination of these two experimental methods allows investigating ... -
Optische Eigenschaften von verdünnten magnetischen Halbleitern auf GaN-Basis
(2008-06-26)Various GaN-based diluted magnetic semiconductors (DMS) were characterized in the course of this work. The main topic was GaMnN and there especially the relation between growth conditions ... -
Optogenetic Control of Cardiac Arrhythmias
(2022-01-04)The regular, coordinated contraction of the heart muscle is orchestrated by periodic waves generated by the heart’s natural pacemaker and transmitted through the heart’s electrical conduction system. Abnormalities occurring ... -
Orbital-order phase transition and non-adiabatic quantum-classical dynamics in strongly coupled electron-phonon systems
(2023-06-01)This thesis contributes to the investigation of solid-state systems with a strong coupling between electrons and the surrounding atomic lattice (phonons). One focus point of the thesis is the material class of $Pr_{1-x}C ... -
