Apparatus for the control of doped ultracold quantum gases

• Subject Area: Optics, Quantum Optics and Physics of Atoms, Molecules and Plasmas
• Term: Funded in 2025
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 564094281

The selective doping of quantum gases with individual atoms of a different element allows experimentally addressing a whole range of scientific questions at the interface between classical and quantum physics in a controlled manner. These include questions of quantum thermodynamics, quantum information processing, or diffusion in complex and driven environments. This apparatus provides the laser sources to dope a quantum gas of rubidium atoms with single or few cesium atoms, and to position and detect the two species independently. It thus provides the basis for experimentally investigating fundamental questions of open systems at the boundary to the quantum world.
