Controlling and Exploring Quantum Matter Using Ultracold Atoms in Optical Lattices Immanuel Bloch

Thursday, October 11, 2018 - 11:15 to 12:30 Auditorium

More than 30 years ago, Richard Feynman outlined the visionary concept of a quantum simu-lator 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 lattic-es to address fundamental physics questions ranging from condensed matter physics over sta-tistical 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 mat-ter with single atom sensitivity and single site resolution, thereby allowing one to directly im-age individual quantum fluctuations of a many-body system or directly reveal hidden topolog-ical antiferromagnetic order in the fermionic Hubbard model. 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.
