Title: Controlling and Exploring Quantum Matter Using Ultracold Atoms in Optical Lattices

Abstract: More than 30 years ago, Richard Feynman outlined the visionary concept of a quantum simulator for carrying out complex physics calculations. Today, his dream has become a reality in laboratories around the world. In my talk I will focus on the remarkable opportunities offered by ultracold quantum gases trapped in optical lattices to address fundamental physics questions ranging from condensed matter physics over statistical physics to high energy physics with table-top experiment.

For example, I will show how it has now become possible to image and control quantum matter with single atom sensitivity and single site resolution, thereby allowing one to directly image individual quantum fluctuations of a many-body system or directly reveal antiferromagnetic order in the fermionic Hubbard model. I will also show, how recent experiments with cold gases in optical lattices have enabled to realise and probe artificial magnetic fields that lie at the heart of topological energy bands in a solid. Using a novel ‘Aharonov-Bohm’ type interferometer that acts within the momentum space, we are now able to fully determine experimentally the geometric structure of an energy band. Finally, I will discuss our recent experiments on novel many-body localised states of matter that challenge our understanding of the connection between statistical physics and quantum mechanics at a fundamental level.

In 2013, Bloch was awarded the Körber European Science Prize and the International Senior BEC Award. He received the Harvey Prize from Israel's Technion Institute in 2015. He is a member of the German Academy of Sciences Leopoldina and an external member of the Canadian Institute for Advanced Research.
