External Control of Many-Body Quantum Systems
(2021-10-05)
In strongly correlated many-body quantum systems, the complex interplay between a large number of degrees of freedom and the presence of various competing energy scales leads to rich phase diagrams, but also renders these ...
Modularity of strings on F-theory backgrounds
(2022-04-04)
This thesis regards topological string theory on elliptically and genus one fibered Calabi-Yau compactifications to study counting indexes over states in a dual six-, five-, and four-dimensional theory realized by F-theory.
The Hubbard Model on the Honeycomb Lattice with Hybrid Monte Carlo
(2021-11-09)
We take advantage of recent improvements in the grand canonical Hybrid Monte Carlo (HMC) algorithm, to perform a precision study of the single-particle gap in the hexagonal Hubbard model, with on-site electron-electron ...
Fluctuations and dissipation in a Bose-Einstein condensed photon gas
(2021-12-02)
Bose-Einstein condensation, superfluidity and superconductivity are all related phenomena where particles behave as collective quantum systems. The behavior of such systems is treated using quantum statistics and their ...
In Silico Facets of Biochemical Research: Accounts from Protein Folding and Protein-Ligand Interaction Studies
(2020-09-04)
Exponential advancements in computer technology over the last five decades have ubiquitously benefited science and humanity as a whole. Consequent beneficiaries of this surge of computational power include all subfields ......
Measurement of the double polarization observables G and E in neutral and positive pion photoproduction off the proton
(2020-08-14)
The nucleons, as one of the most fundamental building blocks of visible matter, are built up of quarks and gluons. However, the interactions and dynamics inside the nucleons, which are mediated by the strong force and ......
Abbildung und farbtonbasierte Analyse ausgedehnter neuronaler Strukturen
(2021-08-03)
Der Hippocampus ist eine Gehirnregion im mittleren Temporallappen, welcher für die Formung des expliziten Gedächtnisses zuständig ist. Lange Zeit galt der Dentatus Gyrus (DG), eine Region im Hippocampus, als “Eingang“ für ...
Jacobi No-Core Shell Model for P-shell Hypernuclei
(2020-06-19)
Understanding baryon-baryon (BB) interactions in the non-zero strangeness sectors is a crucial step toward one of the ultimate goals of nuclear physics - a unified theory describing interactions among baryons. Due ......
Multi-stage Micropattern Gaseous Detectors for the ALICE TPC Upgrade - Studying and Modelling Charge Transfer and Energy Resolution
(2020-06-23)
With the upgrade of the LHC (Large Hadron Collider) at CERN, the interaction rate of ALICE
(A Large Ion Collider Experiment) will be increased up to 50 kHz for Pb-Pb collisions.
Thus the gated and rate-limited readout ...
Identification of low-valent iron-porphyrins: Electronic structure and reactivity towards CO2 reduction
(2022-01-25)
The need to close the carbon cycle becomes urgent as concentration of CO2 in the earth atmosphere increases exponentially. Electrochemically-mediated conversion of CO2 into biofuels is a possible ...
