We demonstrate a cavity-based solution to scale up experiments with ultracold atoms in
optical lattices by an order of magnitude over state-of-the-art free-space lattices. Our two …

We present a detailed investigation of the ultranarrow magnetic-quadrupole S 0 1-P 2 3
transition in neutral strontium and show how it can be made accessible for quantum …

In this work, we implement a new method for imaging ultracold atoms with subwavelength
resolution capabilities and determine its regime of validity. It uses the laser-driven interaction …

We describe Doppler spectroscopy of Bose-Einstein condensates of ytterbium atoms using a
narrow optical transition. We address the optical clock transition around 578 nm between the …

We determine the frequency of the ultranarrow Sr 87 S 0 1-P 2 3 transition by spectroscopy
of an ultracold gas. This transition is referenced to four molecular iodine lines that are …

We investigate a species selective cooling process of a trapped SU (N) Fermi gas using
entropy redistribution during adiabatic loading of an optical lattice. Using high-temperature …

We present measurements of the optical Feshbach resonances (OFRs) of Yb 174 atoms for
the intercombination transition. We measure the photoassociation (PA) spectra of a pure Yb …

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 …

Imaging and manipulating individual atoms with submicrometer separation can be
instrumental for quantum simulation of condensed matter Hamiltonians and quantum …

We describe the construction and characterization of a new apparatus that can produce
degenerate quantum gases of strontium. The realization of degenerate gases is an …
