Non-Markovian open quantum dynamics from dissipative few-level systems to quantum thermal machines
Dissertation(Universität Ulm, 2020-02-07)This cumulative thesis presents new advances in the field of non-Markovian dynamics of open quantum systems based on the formally exact and non-perturbative stochastic Liouville-von Neumann (SLN) framework. More specifically, ... -
Non-classical processes in quantum mechanics : a resource theory approach to characterize coherence
Dissertation(Universität Ulm, 2020-02-06)In the works leading to this thesis the aim was to give a clear operational interpretation of different aspects of non-classicality. Doing so, enables to see the different properties as different aspects of the same ... -
ORR activity and stability of Pt-based and Pt-free catalysts for PEMFC applications
Dissertation(Universität Ulm, 2020-01-24)Aiming at the development of stable and highly ORR active catalysts for PEMFC applications, different Pt-based and Pt-free catalyst materials were developed and characterized regarding their physical and electrochemical ... -
Hyperpolarization and sensing with color centers in diamond
Dissertation(Universität Ulm, 2020-01-16)During the last decade, nitrogen-vacancy (NV) centers in diamond have gained a prominent role within the field of quantum technologies. These color defects inside the diamond lattice have been proved to be an extraordinary ... -
State-to-state chemistry with ultracold neutral Rb atoms
Dissertation(Universität Ulm, 2020-01-07)In this thesis, I report on experiments on the detection and the production of molecules in an ultracold atomic gas. These experiments can be divided into two main parts. The first part is about state-to-state experiments ... -
Novel concepts for ultra-cold quantum gases in microgravity : equal trap frequencies, atoms trapped by atoms, and the space atom laser
Dissertation(Universität Ulm, 2019-12-19)The first realization of Bose-Einstein condensation in 1995 has revolutionized the field of atomic physics and lead to the demonstration of a plethora of new phenomena and applications ever since. Shortly afterwards mixtures ... -
Synthesis and supramolecular chemistry of strained carbon nanohoops
Dissertation(Universität Ulm, 2019-12-18)The central goal of this thesis was to tackle the challenging synthesis of strained carbon nanohoops and explore their applications in supramolecular chemistry as well as material science. Strained carbon nanohoops are ... -
Protective niches for aged hematopoietic stem cells
Dissertation(Universität Ulm, 2019-12-09)Bone marrow hematopoietic stem cell (HSC) niches are composed of multiple hematopoietic and non-hematopoietic cells interacting with HSCs in a complex 3-dimensional architecture to support HSC function. Upon aging, HSC ... -
Electrochemical microbiosensors and improved immobilization strategies for life sciences applications
Dissertation(Universität Ulm, 2019-12-03)Adenosine triphosphate (ATP), as an important macroergic substance in all living cells, plays an important role in various vital biological processes [1]. For example, ATP is released by eukaryotic cells and functions as ... -
Josephson photonics and Josephson scanning tunneling microscopy : inelastic charge transfer across superconducting junctions
Dissertation(Universität Ulm, 2019-11-28)This thesis presents seven publications from the fields of Josephson photonics and Josephson scanning tunneling microscopy in a comprehensive scientific context. In these two new and developing areas of mesoscopic physics, ...
