Abstract

Ultracold atoms in well-controlled engineered environments in optical lattices are a versa-tile tool for quantum-simulation of strongly correlated quantum systems. The most recent developments in this field include quantum-gas microscopes [1], enabling single-lattice-site resolution and single-atom control [2]. Imaging of with single-atoms resolution has made it possible to directly observe bosonic and fermionic many-body quantum systems in an un-precedented way, giving access to, e.g., in-situ measurements of temperature and entropy distributions, direct observation of correlations and their spreading, or the build-up of en-tanglement. I will present how we achieved single-atom-resolved fluorescence imaging of fermionic potassium-40 atoms using electromagnetically-induced-transparency (EIT) coo-ling [3], and a new way of Raman gray-molasses cooling [4]. I will also report on our pro-gress towards the creation of fermionic Mott insulators and the study of strongly correlated fermionic quantum systems and their out-of-equilibrium dynamics.

Referent: Prof. Dr. Stefan Kuhr (University of Strathclyde, Glasgow)
