We experimentally realize a spin-momentum lattice with a homogeneously trapped Fermi
gas. The lattice is created via cyclically rotated atom-laser couplings between three bare …

Symmetries play a crucial role in understanding phases of matter and the transitions
between them. Theoretical investigations of quantum models with SU ($ N $) symmetry have …

We report on the direct optical production and spectroscopy of 1 S 0-3 P 0 molecules with
large binding energy using the clock transition of 171 Yb, and on the observation of the …

In this work I describe the setup of a new quantum gas microscope. The goal of the
experiment is the simulation of topological many-body systems in lattices. Caesium was …

This thesis reports on the experimental realization of the 3D SU (N) Fermi-Hubbard model
and the direct probing of the equation of state with an ultracold quantum gas of fermionic …

This thesis reports on the creation of a state-dependent optical lattice for two-orbital
ytterbium quantum gases and the observation of a tunable interorbital spin-exchange …

We study finite-temperature properties of ultracold four-component mixtures of alkaline-earth-
metal-like atoms in optical lattices that can be effectively described by the two-band spin-1/2 …

Optical atomic clocks with high precision allow minute frequency shifts to be measured in
short timescales. Low instability requires an atomic frequency reference with a high quality …

In the last decade, the development of extraordinary experimental techniques in the field of
atomic physics, as well as in nanotechnology and photonics, allowed for a huge step in the …

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