Quantum Gases Group
At temperatures close to absolute zero neutral atoms offer an ultimate degree of control over all system parameters. We investigate bosonic, fermionic and mixed quantum gases in different trapping potentials like triangular and hexagonal optical lattices and explore the fascinating world of quantum mechanical many-body phenomena.
Our group works at the forefront of current quantum gas research: quantum magnetism, topological quantum matter, optical atomic clocks and single-atom imaging. Beyond that we explore the interplay of ultracold gases with solid state systems and ultra-short light pulses.
If you are interested in joining our highly motivated team at any level of scientific career, please contact Prof. Dr. Klaus Sengstock.
Overview of the research topics
Important research structures
Functionalities are at the heart of the cluster of excellence „CUI: Advanced Imaging of Matter“. Atoms bind together and form solids, molecules interact and react - new functionalities emerge with increasing complexity and growing system size. 160 scientists from different disciplines such as physics, chemistry, and structural biology have joined forces to observe, understand, and control these processes.
The quantum gases group is a central part of research area A of the cluster. Klaus Sengstock is together with Henry Chapman and Horst Weller speaker of AIM.
The SFB 925 "Light induced dynamics and control of correlated quantum systems" addresses the dynamics of the many – one of the deepest and most challenging problems in modern physics: How does collective behaviour emerge from the interactions of multiple degrees of freedom, especially when the system is driven away from equilibrium? The spectacular advances in photon science with new sources of THz and X-ray radiation, in quantum gas physics and in many-body physics have put us in a unique position to tackle this prob-lem comprehensively: We will go beyond imaging the quantum dynamics and reach out to steer many-body states with light to reach new emerging functionalities.
The quantum gases group acts with four projects within SFB 925. Klaus Sengstock is the speaker of this SFB.
Dr. Christof Weitenberg from the Institute of Laser Physics at Universität Hamburg received an ERC Starting Grant (2019-2023) of the European Research Council (ERC) worth € 1.5 million. He will be analyzing exotic particles within the new research project “Engineering and exploring anionic quantum gases”, ANYON in short. Such particles, which are called anyons, can be found in specific systems only and are rarely investigated.
The Research Unit (Forschungsgruppe) FOR 2414 brings together researchers in different cities working on "Artificial Gauge Fields and Interacting Topological Phases in Ultracold Atoms" and is an important platform for scientific exchange.
