Optical plane selection in a dipole trap
(2021-12-17)
Quantum technology has advanced considerably within the last decades [1, 2]. Quantum simulators are among the primary goals of this ongoing „quantum revolution“ [3]. They promise insight into many-particle phenomena that ...
Phenomenology of U(1)Lμ-Lτ Gauge Extension of the Standard Model at LHC
(2021-04-26)
Extending the Standard Model (SM) by a U(1)_{L_mu-L_tau} group gives potentially significant new contributions to g_mu-2, allows the construction of realistic neutrino mass matrices, incorporates violation of lepton ...
Halo bias renormalisation
(2020-06-09)
Modern galaxy redshift surveys provide a wealth of information about the evolution of our Universe. They allow to measure both the two-dimensional position on the sky and the distance (given by the cosmological redshift) ...
Experimental studies on small diameter carbon dioxide evaporators for optimal Silicon Pixel Detector cooling
(2020-12-18)
Since recent years the Large Hadron Collider at CERN and its experiments are the subject of upgrade programs, which are necessary to increase the foreseen collision rates and the amount of data to be gathered for the ...
Exploring Non-Equilibrium in Ultracold Fermi Gases and Machine Learning in Physics
(2021-05-21)
This thesis covers two fields of research carried out in the context of ultracold Fermi gases: Non-equilibrium physics in the BEC-BCS crossover and the use of machine learning methods in physics.
The BEC-BCS ...
The BEC-BCS ...
A formalism for a consistent treatment of two-pion interactions in heavy meson decays
(2020-10-14)
The best-established theory of particle physics up to now is the Standard Model. The theory of strong interactions called quantum chromodynamics (QCD) is a part of it. QCD leads to a wide range of phenomena, which still ...
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 ...
Characterization and Quality Control of RD53A Readout Chips and Modules for the ATLAS ITk Pixel Detector
(2021-12-16)
In preparation of the upcoming high-luminosity upgrade of the Large Hadron Collider, the detectors of the major high-energy physics experiments at the accelerator facility will be upgraded as well. In case of the ATLAS ...
Low Dimensional Gauge Theories and Quantum Geometry
(2020-10-14)
This thesis explores the connection between supersymmetric gauge theories on curved spaces of dimensions two and three and geometries that arise in string theory. It does so by studying quantum field theoretic objects such ......
Λ(1405) photoproduction with the BGO-OD experiment
(2020-05-14)
The Λ(1405) has been considered for many years a candidate for an unconventional hadronic state.
Being difficult to understand within the framework of a three valence quark, constituent quark model,
models explicitly ...
