Peter Schauss

Using the recently developed techniques of quantum gas microscopy, Peter Schauss is working on quantum simulation of bosonic and fermionic quantum many-body systems with ultracold atoms in optical lattices. The single-site and single-atom resolved imaging of these systems enables a unique view on strongly correlated condensed-matter-like systems with full tunability of all relevant parameters of the Hamiltonian, reaching into regimes where exact calculations on classical computers become inaccessible.

Our experimental system relies on the well-developed techniques of laser-cooling and atom trapping. These allow to cool atoms into the quantum regime at a few billionth of a degree above absolute zero, where the particle statistics, i.e. whether the atoms are bosons or fermions, is dominating. By loading ultracold atoms into optical lattices, very clean realizations of a wide variety of condensed matter models are obtained.
This experimental platform is extremely versatile and previous studies have demonstrated precise measurements of properties of quantum materials. Examples include Hubbard models that are related to high-temperature superconductivity, as well as various types of quantum magnets and topological states. In addition, long-range interactions in these system can be introduced by coupling to Rydberg states.

The fresh new view on condensed matter model systems provided by ultracold atoms can help to identify the essence of the physics in these systems. These insights then provide guidance to the understanding of real-world quantum materials with competing quantum effects and their dynamical properties.
