Classical electronic circuits have proven powerful to study topological lattice structures. At the same time quantum simulators reach for increasingly complex lattice gauge theories with the goal of simulating processes in high energy physics. This …

This thesis reports on the experimental realization of an elementary building block for analog quantum simulation of a U(1) lattice gauge theory in a mixture of two bosonic quantum gases. Experimentally, the building block is realized by …

The aim of this work is to explore practical implementations of Quantum and Quantum-assisted Machine Learning algorithms and benchmark potential benefits of utilizing quantum phenomena in Quantum-assisted Neural Networks with qubit layers. Two known …

In atomic physics experiments, setting the magnetic field strength allows one to create spin dynamics between atoms, or to tune the interaction between them. This makes stable magnetic fields desirable, but unfortunately no commercially available …

This thesis describes the construction of a second generation, ultracold atomic mixture experiment, aiming for modularity, robustness and compactness. The setup is designed to work with Bose-Fermi (23Na, 40K) and Bose-Bose (23Na, 39K) mixtures. The …

This thesis describes the construction of a new apparatus to study quantum gas mixtures of sodium and potassium. Our experimental approach entails, using two independent two-dimensional magnetooptical traps (2D MOTs) as sources of cold atoms for a …

This thesis presents design and characterization of a versatile optical standingwave trap for lithium atoms. Using this trap, an implementation of a quantized Otto cycle with the sodium-lithium mixture experiment that cools down a cloud of sodium …

This thesis presents the design and implementation of a high resolution objective lens for imaging ultracold atomic clouds of sodium and lithium in the NaLi experiment. The lens has been developed using the ray tracing software OSLO. The design …

In this thesis we study the quantum transport of matter waves with ultracold atoms. Such ultracold atom systems provide a very good control and a high flexibility of the parameters of the systems like the interactions, its dimensionality and the …
