Identification and understanding of the evolution of interference patterns in two-particle
momentum correlations as a function of the strength of interatomic interactions are important …

The behavior of quantum many-body systems in nature is often an issue of great complexity.
Hence, instead of describing those systems entirely, we tend to extract particular …

This thesis presents correlation measurements in two different few-fermion systems of
ultracold 6Li atoms. The measurements have been performed with a new spatially and spin …

Many of the advantages that the flourishing fields of quantum technologies and quantum
information theory achieve over their classical counterparts rely on quantum correlations …

The emergence of collective and universal behaviour is at the heart of many of the exotic
phases of matter that challenge our physical understanding until today. Fermionic …

This thesis reports on the first realization of a two-particle Laughlin state–the quintessential
building block of fractional quantum Hall states–in a rotating ultracold quantum gas. Utilizing …

This thesis reports on experiments investigating the emergence of many-body physics in
mesoscopic two-dimensional (2D) few-fermion systems. The starting point are low-entropy …

In this thesis, I present and discuss correlation measurements of fermionic quantum systems
engineered out of ultracold 6Li atoms in optical potentials. A strong emphasis is placed on …

[en] In this thesis, experiments performed in a quantum simulator for the two-dimensional
and an extended Hubbard model are presented. The lowest two hyperfine states of …

In this thesis, experimental work is presented which enabled few atom counting in a tweezer-
based K40 setup, the creation of 3D Bose-Einstein condensates of K39, the achievement of …
