Strong Coupling between Small Atomic Ensembles and an Open Fiber Cavity
(2018-04-12)
In this work I present the experimental realization of a versatile platform for the interplay between light and matter at the single-quanta level. In particular, I demonstrate the high cooperativity of small ensembles of ......
Design eines neuen Lichtpulsersystems sowie Aufbau und Inbetriebnahme der neuen APD Auslese für das Crystal-Barrel-Kalorimeter
(2018-02-21)
Um ein tieferes Verständnis von der Struktur der Nukleonen sowie der starken Wechselwirkung zu erhalten, werden am CBELSA/TAPS-Experiment Doppelpolarisationsmessungen in der Meson-Photoproduktion durchgeführt. Die ...
Nuclear Lattice Investigations of Fundamental Symmetries
(2018-04-10)
Fundamental symmetries (and their violations) play a significant role in active experimental searches of Beyond the Standard Model (BSM) signatures. An example of such phenomena is the neutron Electric Dipole Moment (EDM), ......
EPR distance measurements using triaryl methyl radicals and EPR investigation of electron transfer processes in organic radicals
(2018-04-17)
EPR is a valuable tool for the investigation of biological structures. Most EPR-based distance measurements rely on the site directed spin labeling of the investigated biomolecule, since most biomolecular structures do not ...
Nucleon-nucleon scattering process in Lattice Chiral Effective Field Theory approach up to next-to-next-to-next-to-leading order
(2018-04-23)
We carry out a comprehensive analysis of the neutron-proton interaction up to the third order in the scheme of chiral effective field theory on the lattice. The complete two-pion exchange potential is taken into account ...
Exploration of advanced CMOS technologies for new pixel detector concepts in High Energy Physics
(2018-04-19)
This thesis presents the author’s original concepts for the development of radiation hard monolithic pixel sensors that can replace hybrid pixel sensors in high energy physics experiments. It presents one of the first ...
Measurements of differential t-channel single top-quark production cross-sections in proton–proton collisions at a centre-of-mass energy of 8 TeV with the ATLAS detector
(2018-03-28)
Proton-proton collision data at a centre-of-mass energy of 8 TeV recorded with the ATLAS detector in 2012, corresponding to an integrated luminosity of 20.2 fb-1, are used to measure absolute and normalised ...
Investigations into the DNP characteristics of electron and proton irradiated polyethylene and polypropylene
(2018-03-06)
To achieve a significant enhancement of the nuclear polarisation of solid state target materials one must use the method of dynamic nuclear polarisation. This necessitates unpaired electrons, that can be created as ...
Modulation Spectroscopy of Ultracold Atoms in Optical Lattices
(2018-03-12)
In the past fifteen years ultracold atoms confined to optical lattices, which are artificial crystals of light, have proven to be powerful tools in the study of strongly correlated many-body systems widely known from a ......
Probing the top-quark coupling to the photon through the cross-section measurement of ttγ production in pp collisions with the ATLAS detector
(2018-07-03)
The cross section of top-quark pair production in association with a photon is measured in proton-proton collisions at a centre-of-mass energy of 8 TeV with 20.2 fb-1 of data and at 13 TeV with 36.1 fb-1 ...
