Dynamical Gauge Fields
Within the Standard Model of Particle Physics, the interaction between fundamental particles is described by gauge theories. These theories have an enormous predictive power, but to compute the dynamics they generate is an extremely hard task. As a consequence, high-energy physics contains many unsolved problems such as quark confinement or the dynamics of quarks and gluons during heavy-ion collisions. Instead of computing them in classical devices or investigating them in enormous accelerator facilities, we aim at implementing lattice gauge theories on the optical table by having atomic gases in optical lattices mimic the interplay between particles, anti-particles, and gauge bosons. In this way, experiments at temperatures just above absolute zero could give insights into unsolved phenomena that in Nature appear at very high energies.

A next-generation machine for Bose-Fermi mixtures
Given the wide-ranging applications of atomic Bose-Fermi mixtures for the investigation of fundamental physics, we are designing a next-generation experimental set-up.
Based on our experience with the existing machines, we will construct a set-up with improved speed, flexibility and precision.
