Controlled loss in a quantum gas through narrow line photo association

15 May 2017

Open quantum systems, which are closely related to real-world systems are inherently difficult to realize with ultracold quantum gases due to their excellent decoupling from all environmental influences. Narrow line photo association (PA), as it is possible to implement with alkaline-earth like elements such as Yb, allows for the introduction of a controllable loss channel. Many interesting phenomena are expexted to occur in a quantum gas in an optical lattice with dissipative interaction, namely the transition from a Mott- to a Quantum Zeno insulator or the  generation of highly entangeld many-body states.

In your Master project, it will be your task to characterize several PA resonances in Yb173 and conduct first measurements in a dissipative Fermi Hubbard system.
