Non-Markovian Dynamics of Open Bose-Einstein Condensates
(2021-03-08)
Quantum many-body systems coupling photonic and matter degrees of freedom are ideal for the realization of driven open quantum dynamics at the intersection of quantum optics and condensed matter. They offer the possibility ...
Variable Potentiale für thermisches Licht und gekoppelte Photonenkondensate
(2018-01-16)
Seit mehr als einer Dekade lassen sich mit ultrakalten Atomen in periodischen Gitterpotentialen viele Aspekte der Festkörperphysik an sehr reinen, künstlichen Kristallen studieren. So konnte beispielsweise der Übergang von ...
Final-state interactions in heavy-meson decays
(2018-08-15)
In the last decade the investigation of the heavy-meson sector has gained in importance, in particular for precision tests of the Standard Model and exploration of the physics beyond, such as CP violation. Experimentally, ...
Vector-meson interactions, dynamically generated molecules, and the hadron spectrum
(2018-09-19)
We study the lowest-lying vector-meson interactions and dynamically generated bound states. Therefore, these bound states are studied as hadronic molecules. We demonstrate that some unitarization methods are not well-defined ...
Knotenwichtigkeiten in räumlich ausgedehnten dynamischen Systemen
(2018-08-28)
Ausgedehnte komplexe dynamische Systeme können eine Vielzahl von faszinierenden emergenten Phänomenen aufweisen. Viele solcher Systeme bestehen aus einer großen Anzahl interagierender Subsysteme. Es bietet sich daher an, ...
Yukawa Couplings from D-branes on non-factorisable Tori
(2018-08-15)
In this thesis Yukawa couplings from D-branes on non-factorisable tori are computed. In particular intersecting D6-branes on the torus, generated by the SO(12) root lattice, is considered, where the Yukawa couplings arise ...
Test beam and simulation studies on High Resistivity CMOS pixel sensors
(2018-09-21)
The Compact Linear Collider CLIC is an option for a future electron positron collider at CERN, with a centre of mass energy up to 3 TeV. The demanding physics goals at CLIC require a lightweight silicon vertex detector and ...
Associated Production of a Top Quark and a Z Boson in pp Collisions at √s = 13 TeV Using the ATLAS Detector
(2018-09-26)
The production of a top quark in association with an Z boson is studied using 36.1 fb-1 of proton-proton collision data collected by the ATLAS experiment at the LHC in 2015 and 2016 at a centre-of-mass ...
Search for solar chameleons with an InGrid based X-ray detector at the CAST experiment
(2018-08-15)
Chameleons are particles with a density dependent effective mass and couplings to matter as well as photons. They are introduced in modifications to General Relativity involving scalar fields and aiming at explaining Dark ...
Transporteigenschaften und Reaktivität von Bor-hydrid-hydrat-oxidsodalithen
(2018-07-13)
In dieser Arbeit wurden Borsodalithe bezüglich ihrer Eignung als Wasserstoffspeicher und BH$_4^-$-haltige Salze in Kooperation mit der experimentellen Arbeitsgruppe textit{Rüscher} quantenchemisch mit periodischen ...
