Quantum Optics Group (LMU) - Quantum Many Body Systems Division (MPQ)


Welcome! We are carrying out research in the field of quantum optics and quantum many-body systems using ultracold atomic and molecular quantum gases at the Max Planck Institute of Quantum Optics and the Ludwig Maximilians University. Furthermore, our group is part of the Munich Quantum Center.

We are always looking for Master students, PhD students and Postdocs. For more information click here! 

Breaking down our research so that 99,999% of the worlds population would understand it, was the goal of Jayadev Vijayan with his article "Zooming into superconducters". With his Leap - a popular science article on quantum research written by scientists and reviewed by teenagers — published in Quantum Views, he explains his research to 13-14 year old High School students who reviewed the article and (hopefully!) understood why cold atoms is a research field worth studying.

Professor Dan Stamper-Kurn has won a Humboldt Research Award

The award is conferred on established investigators from abroad to enable them to undertake collaborative projects with designated colleagues in Germany. Moreover, the Board of Directors of the Max Planck Institute of Quantum Optics has honoured Prof. Stamper-Kurn an MPQ Distinguished Scholar, in appreciation of his groundbreaking contributions to the field of Ultracold Quantum Gases and Quantum Optics. Prof. Stamper-Kurn arrived in Munich in January 2018, where he is pleased to be hosted by Prof. Immanuel Bloch. He is Professor at the University of California in Berkeley, he is also affiliated with the Materials Sciences Division at the Lawrence Berkeley National Laboratory and heads the Science Definition team of the Bose-Einstein Condensation Cold Atom Laboratory (BECCAL) – a collaborative endeavor of the German Aerospace Center (DLR) and NASA that aims to conduct quantum gas experiments aboard the International space Station (ISS).

On Tuesday, March 6th 2018, Frauke Seeßelberg received the first price for her presentation at the EinsteinSlam.

EinsteinSlam is the competitive art of making complex science accessible to a broad audience. There are just 10 minutes for every attendee to present his/her self-made performance.

A single-particle mobility edge (SPME) marks a critical energy separating extended from localized statesin a quantum system. In one-dimensional systems with uncorrelated disorder, a SPME cannot exist, since all single-particle states localize for arbitrarily weak disorder strengths. However, in a quasiperiodic system, the localization transition can occur at a finite detuning strength and SPMEs become possible. In this work, we find experimental evidence for the existence of such a SPME in a one-dimensional quasi-periodic optical lattice. Specifically, we find a regime where extended and localized single-particle states coexist, in good agreement with theoretical simulations, which predict a SPME in this regime.
