We experimentally study the emergence of antiferromagnetic correlations between ultracold
fermionic atoms in a two-dimensional optical lattice with decreasing temperature. We …

We propose a cold-atom realization of a zigzag ladder. The two legs of the ladder
correspond to a “synthetic” dimension given by two internal (spin) states of the atoms, so that …

Within one-dimensional disordered models of interacting fermions, we perform a numerical
study of several dynamical density correlations, which can serve as hallmarks of the …

The periodic Anderson model (PAM), where local electron orbitals interplay with itinerant
electronic carriers, plays an essential role in our understanding of heavy fermion materials …

Im letzten Jahrzehnt haben sich Quantengasexperimente als gut kontrollierbare
Modellsysteme zur Untersuchung komplexer Fragestellungen aus diversen Bereichen der …

This thesis describes an investigation of Rydberg excitation within a high-density sample of
cold strontium atoms. This sample is prepared using a two-stage magneto-optical trap …

Ultracold quantum gases in an optical lattice enable us to study a strongly correlated system.
The single-site-resolved imaging and the single-site addressing technique, called a …

The Fermi liquid theory is a central concept in modern condensed matter physics used to
describe conventional metals. A state of this universality class consists of well-defined …
