Fabry-Pérot etalons for high precision radial velocity calibration
(2014-06-24)The current generation of astronomical spectrographs can measure radial velocity signals of exoplanets down to a few m/s, in ideal cases even 60 cm/s can be achieved. This led to the discovery of rocky planets with masses ... -
Far-from-Equilibrium Quasiparticle Dynamics in Graphene
(2023-01-17)Comprehending far-from-equilibrium many-body interactions is one of the major goals of current ultrafast condensed matter physics research. Here, a particularly interesting but barely understood situation occurs during a ... -
Faseroptische Gemischbildungsanalyse in Otto-Motoren bei direkteinspritzenden Brennverfahren
(2005-01-12)The mixture formation process in gasoline direct injection engines is very complex and depends strongly on thermodynamic processes mainly induced by the engine geometrie. Most of the optical ... -
Fast STED Microscopy
(2010-02-12)The spatial resolution of optical far-field microscopes was hampered by diffraction until STED microscopy broke the diffraction limit. This thesis for the first time combines the high spatial ... -
Fast, Three-Dimensional Fluorescence Imaging of Living Cells
(2022-01-21)This thesis focuses on multi-plane fluorescence microscopy for fast live-cell imaging. To improve the performance of multi-plane microscopy, I developed new image analysis methods. I used these methods to measure and analyze ... -
Feldinduzierte Tieftemperaturoxidation nanoskaliger Metall- und Halbleiterstrukturen
(2008-12-04)At the surface of almost all metals and semiconductors oxide formation occurs when exposed to atmosphere. The oxidation reaction proceeds along a number of partial reaction steps with the ... -
Ferromagnetismus bei Raumtemperatur in mehrphasigen (Ga,Mn)N Schichten und Heterostrukturen
(2009-09-15)(Ga,Mn)N is a GaN-based dilute magnetic semiconductor (DMS) and thus a promising system for semiconductor spintronic applications. Within the scope of this thesis thin layers of Mn doped ... -
Fest-Flüssig Übergänge in Schüttgütern
(2009-08-04)In this thesis, the stability and the dynamics of wet granular materials under shear are explored. Inspired by the Green"s function approach, a theoretical model for yielding of a wet pile ... -
Fiducial cross-section measurements of the production of a prompt photon in association with a top-quark pair at $\sqrt{s}=13$ TeV with the ATLAS detector at the LHC
(2018-11-23)The cross sections for top-quark pair production in association with a photon are measured in a fiducial volume with the ATLAS detector at a centre-of-mass energy of 13 TeV. Results are presented using proton-proton collision ... -
Finite-temperature dynamics of low-dimensional quantum systems with DMRG methods
(2016-08-17)This thesis is concerned with the numerical study of one-dimensional (1D) spin-1/2 quantum magnets and related method development. Its focus is on the calculation of dynamical spin correlation functions both at zero and ... -
First-principles calculations of polaronic correlations and reactivity of oxides: manganites, water oxidation and Pd/rutile interface
(2019-05-28)The electronic, magnetic and atomic structure of Pr1−xCaxMnO3 have been investigated using combination of first-principles calculations, x-ray photoelectron spectroscopy (XPS), x-ray absorption spectroscopy (XAS), and ... -
Fluctuational electrodynamics for nonlinear materials in and out of equilibrium
(2019-05-16)Fluctuational electrodynamics (FE) is a successful and well established theory. By making use of the fluctuation dissipation-theorem (FDT), it ties together the linear response (Green's function) and the strength of thermal ... -
Fluid instabilities in precessing ellipsoidal shells
(2002-02-06)The Earth precesses with a period of 25700 years due to the gravity fields of the Moon and the Sun acting on the Earth's equatorial bulge. The influence of the Earth's precessional motion ... -
Fluorescence nanoscopy in three dimensions
(2010-03-11)Live-cell microscopy faces two challenges when neither the spatial nor the temporal information about the specimen should be lost. First, the microscope must be able to resolve the smallest ... -
Follow-up and dynamical analysis of Kepler targets with transit timing variations
(2020-06-04)The exact characterisation of planets, their host stars and the structure of their systems is an essential part of exoplanet research. This helps to understand the formation and evolution of planetary systems. Planets ... -
