Periodically driven topological non-interacting and interacting quantum lattice systems
(2022-05-27)
Periodically driven quantum lattice systems are nowadays reachable in the laboratory. Those systems, which can host exotic non-equilibrium phases and phenomena, attract intensive theoretical studies. In this thesis, we use ...
A memory-based quantum network node with a trapped ion in an optical fibre cavity
(2022-06-17)
Exploiting quantum effects in the communication between different systems promise great capabilities as distributed quantum computing or provably secure communication. In this thesis we present the realisation of a ...
Quanten-Rabi Dynamik ultrakalter Atome im Bereich der tiefen starken Kopplung
(2022-06-21)
Das Quanten-Rabi Modell ist eines der einfachsten quantenmechanischen Modelle zur Beschreibung der Wechselwirkung von Licht und Materie als Kopplung einer bosonischen Feldmode und eines Zwei-Niveau-Systems. Während das ...
Measurement of the top quark decay branching fraction ratio Rb = B(t → Wb)/B(t → Wq) and of the inclusive production cross section pp → tt in the dilepton channel at ATLAS
(2022-01-13)
The top quark branching fraction ratio Rb and the inclusive production cross section σ tt̄ are measured in the dilepton channel using 4.6 fb-1 of proton-proton collisions at the centre-of-mass ...
Probing the quantum speed limit of atomic matter waves in optical lattices
(2021-09-21)
The development of quantum technologies requires a deep knowledge of quantum systems and a high level of control of quantum states. In this thesis I report on my contribution to three areas that are important to quantum ...
New Insights into the Milky Way Magnetic Fields through Radio Broadband Spectro-polarimetry
(2020-03-05)
Magnetic field is an essential ingredient of the interstellar medium of galaxies. In particular, an accurate characterisation of the magnetic field strength and structure of the Milky Way is crucial for complete understanding ...
Dark Matter Phenomenology at Colliders
(2020-02-26)
Dark Matter candidates are required in physics beyond the Standard Model. The preferable models should not only explain the observed phenomena, but also be testable by experiments including direct detection, indirect ...
Study of Excited Ξ Baryons in Anti-Proton Proton Collisions with the PANDA Detector
(2020-02-11)
Understanding the excitation pattern of baryons is indispensable for the understanding of non-perturbative QCD. Up to now only the nucleon excitation spectrum has been subject to systematic experimental studies, in contrast ...
Lepton Flavor Violation Phenomenology Beyond the Standard Model
(2020-03-12)
Historically, experimental searches for flavor violating processes have been essential for the theoretical developments in Particle Physics. After the detection of neutrino oscillations, the most clear experimental evidence ...
Nonequilibrium Dynamics of Correlated Fermi Gases
(2020-10-26)
Strongly correlated quantum systems display a myriad of complex, fascinating behaviour. The competition between charge, spin, orbital, or lattice degrees of freedom and their respective energy scales gives rise to rich and ...
