Quantitative proteome analysis of S-nitrosylation on synaptosomal proteins in Alzheimer's disease
Wijasa, Teodora Stella (2019-08-28)Alzheimer's disease (AD) is an irreversible, progressive and most common type of dementia in the aging population. AD pathophysiology starts slowly and deteriorates over time before the clinical diagnosis of dementia can ... -
Quantum Chemical Calculation of Electron Ionization Mass Spectra
Bauer, Christoph (2018-03-06)This thesis reports the computation of electron ionization (EI) mass spectra using a method that combines statistical theory and molecular dynamics. Due to the complexity of the unimolecular reaction space, not all competing ... -
Quantum cluster algebras and the dual canonical basis
Lampe, Philipp (2011-03-14)Let Q be either a Dynkin quiver of type A with alternating orientation or the Kronecker quiver. With the indecomposable injective modules over the path algebra of Q and their Auslander-Reiten translates we associate an ... -
Quantum Information and Quantum Gravity in Anti-De Sitter and Cosmological Spacetimes
Kames-King, Joshua (2022-09-30)The holographic principle constitutes a guiding principle for the construction of a quantum theory of gravity. While the final goal is the application of such a theory to our own universe, the most concrete instantiation ... -
Quantum Magnetism in the Two-Dimensional Fermi-Hubbard Model and Beyond
Wurz, Nicola Camilla (2022-04-06)Ultracold quantum gases in optical lattices serve as an analogue quantum simulator to investigate the physics of strongly correlated materials. With our quantum gas setup we investigate fermionic potassium atoms in a single ... -
Quantum Phase Transitions in Multi-Impurity and Lattice Kondo Systems
Nejati, Ammar (2017-04-25)The main purpose of this dissertation is to provide a detailed development of a self-consistent perturbative renormalization group (RG) method to investigate the quantum phases and quantum phase transitions of multi-impurity ... -
Quantum simulation of strongly-correlated two-dimensional fermions in optical lattices
Chan, Chun Fai (2020-05-12)In this thesis, I present the experimental realisation of the two-dimensional Hubbard model with ultracold fermionic Potassium-40 atoms in optical lattices. By tuning the dimensionality, kinetic and interaction in the ... -
Quantum Simulation of the Bilayer Hubbard Model Using Ultracold Atoms
Gall, Marcell Wolfgang (2021-09-15)In this thesis, experiments performed in a quantum simulator for the two-dimensional and an extended Hubbard model are presented. The lowest two hyperfine states of fermionic potassium atoms are used to realise the model’s ... -
Quantum Simulation of the Periodic Quantum Rabi Model at Deep Strong Coupling
Hunanyan, Geram (2024-01-16)The quantum Rabi model (QRM) stands as perhaps the most fundamental framework describing qubit-light interaction. While observations of many experiments can already be described within the Jaynes-Cummings model, which ... -
Quantum Statistical Mechanics of Shimura Varieties
Ha, Eugene (2006)The Bost-Connes and Connes-Marcolli C*-dynamical systems are seen to be associated to the Shimura varieties for GL(1) and GL(2), respectively. In this thesis we carry out the construction of Bost-Connes-Marcolli systems ... -
The Quantum Walk Microscope
Brakhane, Stefan (2017-03-02)In this thesis, I present single-site detection of neutral atoms stored in a three-dimensional optical lattice using a numerical aperture objective lens (NA<sub>design</sub> = 0.92). The combination of high-resolution ... -
Quark-mass dependence of pion scattering amplitudes
Niehus, Malwin Leonard Berengar (2022-07-11)We analyze lattice-QCD data of the ππ → ππ P wave obtained at unphysical-high pion masses with the inverse-amplitude method at next-to-leading order and at next-to-next-to-leading order. We then extrapolate to the ... -
Der quartäre Rodderberg-Vulkankomplex südlich von Bonn: vulkanologische und petrogenetische Entwicklung
Ewen, Christine (2008)Der quartäre Rodderberg-Vulkankomplex befindet sich ca. 12 km südlich von Bonn im Übergangsbereich des Rheinischen Schiefergebirges zur Niederrheinischen Bucht und repräsentiert einen typischen kontinentalen Intraplatten ... -
Quasi-Periodicity in the Parsec-Scale Jet of the Quasar 3C 345: A high resolution study using VSOP and VLBA
Klare, Jens (2003)We have observed the Quasar 3C345 with VSOP and the VLBA at four different frequencies (1.6GHz, 5GHz, 22GHz and 43GHz), making a total of 24 epochs, from 1997.40 to 1999.69. This study, combined with previous observations, ... -
The Quest for the η and η' Transition Form Factors: A Stroll on the Precision Frontier
Holz, Simon (2022-10-04)An important precision test of the Standard Model of Particle Physics is posed by the prediction of the anomalous magentic moment of the muon. Currently, a deviation of about 4.2<em>σ</em> persists between the experimental ... -
The Quintuplet cluster: A young massive cluster study based on proper motion membership
Hußmann, Benjamin (2014-01-27)Young massive clusters define the high mass range of current clustered star formation and are frequently found in starburst and interacting galaxies. As - with the exception of the nearest galaxies within the local group ... -
Quiver Modulations and Potentials
Geuenich, Jan (2017-04-11)We introduce DWZ (Derksen-Weyman-Zelevinsky) mutation for a special class of SPs (species with potential). Generalizing a construction of Labardini-Fragoso, we associate with each triangulated, constantly weighted orbifold ... -
