Crystal growth and scattering studies on two ferrites
Jülich : Forschungszentrum Jülich GmbH Zentralbibliothek, Verlag 150 p. (2016) [10.3204/PUBDB-2019-04185] = Dissertation, RWTH Aachen, 2016
In this thesis I will describe investigations of two ferrite systems:(1) A detailed ferroelectric study of magnetite (Fe3O4)Multiferroics, consisting of both ferroelectric and ferromagnetic phases, have attractedscientic and technological interest due possible magnetoelectric coupling between thephases. Such materials are very rare though, as conventional ferroelectricity requires anempty d-shell, preventing the presence of magnetism. [...]

Quantization of super Teichmüller spaces
[DESY-THESIS-2016-021]
Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 157 pp. (2016) [10.3204/PUBDB-2016-03141] = Dissertation, Universität Hamburg, 2016
The quantization of the Teichmüller spaces of Riemann surfaces has found important applications to conformal field theory and N = 2 supersymmetric gauge theories. We construct a quantization of the Teichmüller spaces of super Riemann surfaces, using coordinates associated to the ideal triangulations of super Riemann surfaces.A new feature is the non-trivial dependence on the choice of a spin structure which can be encoded combinatorially in a certain refinement of the ideal triangulation [...]

The observation of strong-field dynamics in atoms and molecules on ultra short timescales has been of high interest for a long time. In recent years the investigation of inner-shell electron dynamics became possible when strong ultrashort lasers in the extreme ultra violet (XUV) became reality in the form of free electron lasers (FEL).

Because of their unique structure, thin films provide an unprecedented view into the fundamental physics of a two-dimensional world. There is also an enormous demand for suchmaterials in applied fields, and many thin films find use as platforms for device applications.To further our understanding of such materials, this thesis investigates the properties ofthin films on the time- and length-scales associated with atomic motions.

Precise measurements of the arrival time jitter between the ionization laser, usedto create the plasma, and the driver beam in the PWFA setup of the FLASHForwardproject are of high interest for the operation and optimization of the experiment.In this thesis, an electro-optic temporal decoding (EOTD) setup with nearcrossed polarizer detection scheme is presented, which can measure the timingjitterto an accuracy of around 30 fs. This result was obtained during severalmeasurements conducted at the coherent transition radiation beamline CTR141at FLASH, using a 100 m thick GaP crystal and coherent diffraction/transitionradiation, generated from the FLASH1 electron bunches.Measurements were performed during long and short electron bunch operationat FLASH, showing that best results are obtained with CDR from long electronbunches.

Measurements of Z boson plus jet production cross section using $\sqrt{s}=8$ TeV data and studies of jet quark-gluon decomposition
[DESY-THESIS-2016-009]
Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 129 pp. (2016) [10.3204/DESY-THESIS-2016-009] = Universität Hamburg, Diss., 2016
A measurement of the differential cross-section of $pp \rightarrow Z/\gamma^{*}(\rightarrow e^{+}e^{-})$~+~jet production and a study of the jet quark-gluon decomposition are presented. The data of 21.3 $\mathrm{fb^{-1}}$ collected with the ATLAS detector at the Large Hadron Collider in 2012 at the centre-of-mass energy $\sqrt{s} = 8$~TeV are used.The double-differential $pp \rightarrow Z/\gamma^{*}(\rightarrow e^{+}e^{-})$~+~jet cross-section is measured as a function of the absolute rapidity and the transverse momentum of jets.

To extract valuable information on the cosmological evolution of the Universe from the observational data, it is of major importance to derive accurate theoretical predictions for the statistical large-scale structure observables, such as the power spectrum and the bispectrum of (dark) matter density perturbations.

Characterization of such devices brings its own challenges and here we show that X-rays offer large possibilities to analyze the structural properties.In the present work we used three different techniques to characterize a large spectrum of different nanowire heterostructures from the structural point of view:(i) First, we measured high resolution three dimensional reciprocal space maps averaged over large number of nanowires.

Ionisation of Hydrogen for Plasma Wakefield Accelerators

In order to describe the electron density of a hydrogen plasma generated via anultrashort laser pulse, it is necessary to understand the underlying ionisation processof the pulse interacting with H2. Simulations and calculations based on thesimplest ADK ionisation thresholds are likely to overestimate the ionisation fractionsince the molecular dynamics in H2 are not included.The tunnelling barrier-suppression (TBSI) model combines atomic ADK theory [2]with an empirical correction far into the barrier-suppression ionisation regime [46],[38], and can also be applied to calculate molecular ionisation rates [39].

Angular Analysis of $B \to K^\ast \ell\ell$ and Search for $B^+\to K^+ \tau \tau$ at the Bellle Experiment

Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 209 pp. (2016) [10.3204/PUBDB-2016-03770] = Dissertation, Universität Hamburg, 2016
Rare decays of $B$ mesons are an ideal probe to search for phenomena beyond the Standard Model of particle physics, since contributions from new particles can affect the decays on the same level as Standard Model predictions.The rare decay of $B \to K^{(\ast)} \ell^+ \ell^-$offers the quark transition $b\to s \ell^+ \ell^-$, a flavor changing neutral current which is forbidden at tree level in the Standard Model.Higher order processes such as penguin or $W^+W^-$ box diagrams allow for these processes, leading to branching ratios of less than one in a million.Various extensions to the Standard Model predict influences of new physics, which can enhance or suppress branching ratios or lead to changes in angular distributions of the decay products. In order to produce a sufficient amount of $B$ mesons, the so-called $B$-factories were designed.One of them is the asymmetric-energy $e^+e^-$ collider KEKB with the Belle experiment, located in Tsukuba, Japan.During 1999 to 2010 the experiment recorded a total luminosity of $1~\mathrm{ab}^{-1}$ of electron positron collisions.

Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 201 pp. (2016) [10.3204/PUBDB-2016-05734] = Dissertation, Universität Hamburg, 2017
Free-electron lasers as accelerator-driven light sources and wakefield-based acceleration in plasmas require the knowledge of the longitudinal extension and the longitudinal current profile of the involved electron bunches. These bunches can yield lengths below 10 µm, or durations shorter than approx. [...]

An atomic perspective of the photodissociation and geminate recombination of triiodide in condensed phases
[DESY-THESIS-2016-028]
Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 162 pp. (2016) [10.3204/PUBDB-2016-03652] = Dissertation, Universität Hamburg, 2016
The thesis presents progress made towards a thorough understanding of the photodissociation and geminate recombination of triiodide anion (I$_3^-$) in solution and solid state using novel time-resolved spectroscopic and structural methods that have matured in the past decade. An isolated I$_3^-$ has only three degrees of freedom, but in the condensed phase, the case of an open quantum system, its chemistry is transformed because other degrees of freedom from the surroundings (the bath) need to be fully taken into account.

Strong-field interaction of solids with terahertz and infrared radiation
121 pp. (2016) [10.3204/PUBDB-2017-00909] = Ruhr-Universität Bochum, Masterarbeit, 2016
In this work we experimentally investigated strong IR and THz electric field light-matter interaction with semiconductor and dielectric solids. During the strong-field IR experiments we observed a generation of a new spectrum for crystalline and polycrystalline diamond samples. [...]

Diffractive Dijet Production with a Leading Proton in $\it ep$ Collisions at HERA
[DESY-THESIS-2016-006]
Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS 144 pp. (2016) = Charles University, Prague, Diss., 2016
The cross section of the diffractive process e+p → e+Xp is measured at a centre-of mass energies of 319GeV, where the system X contains at least two jets and the leading final state proton p is detected in the H1 Very Forward Proton Spectrometer. The measurement is performed in photoproduction defined by photon virtualities Q2 <2GeV2 and in deep-inelastic scattering with 4GeV2 < Q2 < 80GeV2. [...]
