Our paper describing the Li-Cs mixing experimental apparatus has been now published in the journal Few-Body Systems! Experiments involving atomic mixtures with a large mass imbalance face significant challenges in slowing, cooling, and trapping the species together. This paper highlights the development of efficient techniques to address these issues, focusing on three aspects: slowing of hot atoms, managing of dipole traps, and controlling magnetic fields. This machine allowed the investigation of the heteronuclear Efimov effect in the ultracold Li-Cs mixture as reported in several previous publications.

Congratulations to Eleonora Lippi who today defended her PhD thesis “Cs-133 atoms in a Li-6 Fermi sea for exploring polaron physics in the heavy impurity limit”. It has been a wonderful experience working alongside you and we cannot wait to see what the future brings. We wish you the best of luck!

This month, our paper on “Anomalous loss behavior in a single-component Fermi gas close to a p-wave Feshbach resonance” was published in Phys. Rev. A! In this work we studied the theoretical processes of three-body loss in a p-wave interacting Fermi gas. The study predicts a new type of three-body loss behavior in these kinds of systems which could be observed in lithium-6 polarized in the lowest hyperfine groundstate.

A warm welcome to our news PhDs, Micheal and Tobias. Michael starts his PhD after have concluded his master thesis in our group studying the relation between Efimov scenario and Fermi polarons. Tobias joins us from Karlsruhe where he did his master thesis on optical fiber-based micro resonators. Good luck to both!
