Measuring the Gap and Investigating Non-equilibrium in the BEC-BCS Crossover
(2017-09-15)
This thesis presents a new Bose-Fermi mixture quantum gas experiment that has been used to measure the gap over the BEC-BCS crossover and investigate the non-equilibrium dynamics of a superfluid in response to a quench of ...
Spindynamik in Elektronensynchrotronen
(2017-09-29)
Um unser Verständnis des Aufbaus der Materie voranzutreiben sind Experimente mit hochenergetischen Teilchen erforderlich, bei denen alle Eingangsparameter bekannt sind und variiert werden können. Zu diesen gehört auch die ......
Spin Dynamics in Electron Synchrotrons
Providing spin polarized particle beams with circular accelerators requires the consideration of depolarizing resonances which may significantly reduce the ......

Kalorimetrie und Phasenkorrelationen eines zweidimensionalen Photonengases
(2017-08-10)
Phasenübergänge spielen in der Physik eine bedeutende Rolle. Es entspricht unserer Alltagserfahrung, dass Materie ihre Eigenschaften in Abhängigkeit von äußeren Parametern wie Volumen, Druck oder Temperatur bei Überschreiten ...
Searches for Neutrinos from Supernovae Using Cherenkov In-Ice Detectors
(2017-05-15)
Supernovae mark the violent death of massive stars. They are among the most energetic processes known to exist in the Universe. Neutrinos play crucial roles in supernova processes. Besides the low-energy neutrinos emitted ...
Quantum Phase Transitions in Multi-Impurity and Lattice Kondo Systems
(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 ...
Massive stars on the main sequence
(2017-03-10)
Massive stars have a strong influence on their environment by chemical enrichment of the surrounding interstellar medium due to strong stellar winds. The influence of mass loss and rotation on the main-sequence evolution ...
Cosmological Investigations On Large And Small Scales
(2017-03-03)
The standard model of cosmology, founded on Einstein’s theory of gravity and on the Cosmological Principle (CP), has been understood as being successful in providing explanations for many observations so far. However, it ...
Die externe Strahlführung für Detektortests X3ED an der Elektronen-Stretcher-Anlage ELSA
(2017-12-12)
Um das Verständnis des Aufbaus der Materie zu erweitern sind Experimente mit hochenergetischen Teilchen erforderlich. Diese Teilchenstrahlen werden beispielsweise durch Kreisbeschleuniger bereitgestellt. Aufseiten der ...
Hadronic Electroweak Processes in a Finite Volume
(2017-11-27)
In the present thesis, we study a number of hadronic electroweak processes in a finite volume. Our work is motivated by the ongoing and future lattice simulations of the strong interaction theory called quantum chromodynamics. ...
Metal-air Batteries: RRDE and EC-SPM Studies of Electrode Kinetics and Electrode Structure
(2017-09-26)
Metal air batteries are the energy storage devices, which possess the advantages of low cost, non-toxic, non-polluting, high theoretical specific energy, etc. Consequently, they received extensive attention and are considered ...
