Measurements of q2 moments of inclusive B → Xcℓν decays toward an alternative determination of |Vcb|
(2021-12-06)
This thesis presents the first measurement of the first to the fourth moments of the four-momentum transfer squared q2 spectrum for inclusive B → Xcℓν decays, where ℓ = e, μ. The determination of these ......
The structure of massive star-forming clumps
(2021-11-25)
Among many other critical questions in astrophysics, the high-mass star formation process is a matter of heated debate; so far a comprehensive understanding is lacking. Star formation takes place in cold molecular clouds. ...
Quantum Simulation of the Bilayer Hubbard Model Using Ultracold Atoms
(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 ...
Design and characterization of pixel IC electronics and sensors for new pixel detector generations
(2022-03-22)
The LHC High Luminosity upgrade will result in a significant change of environment in which the particle detectors are going to operate, especially for devices very close to the interaction point like the pixel detectors ...
Testing models of galaxy formation and evolution with galaxy-galaxy-galaxy lensing
(2021-03-29)
Explaining the formation and evolution of galaxies is a fundamental issue in modern astronomy. Several competing models try to explain how galaxies form and predict the relationship between galaxies and dark matter. A ...
Quantum simulation of strongly-correlated two-dimensional fermions in optical lattices
(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 ...
Simulation of Bone Remodeling Process around Dental Implant During the Healing Period
(2021-07-05)
This interdisciplinary thesis deals with the numerical investigation of bone remodeling around dental implants during the healing period with regard to biomechanical aspects. The aim of the study was to develop algorithms ...
Weak lensing magnification & baryon acoustic oscillations in galaxy-galaxy lensing
(2021-09-08)
Cosmology is the science that aims to explain the Universe in its entirety. While the standard cosmological model has had tremendous success in explaining independent astrophysical observations, we still lack understanding ...
Experimental Near-Field Characterization of Plasmonic Nanostructures
(2021-01-13)
The spatial resolution of conventional optical technologies is fundamentally limited by diffraction due to the wave nature of light. A promising platform to overcome this diffraction limit in nanophotonic applications is ...
Studies into measuring the Higgs CP-state in H → ττ decays at ATLAS
(2020-07-16)
Since the discovery of the Higgs boson in 2012, experimental particle physics made large efforts to measure all properties of the new particle to characterise all its properties as precisely as possible.
So far, all ...
