Mass-imbalanced Fermi Mixtures (Cr-Li)
Mixtures of two different species of fermionic atoms open qualitatively new opportunities in the realm of ultracold Fermi gases, enabling access to a plethora of few- and many-body regimes unattainable with mass-symmetric systems. In our lab we produce the first chromium-lithium fermionic mixture worldwide. Tuning of the interspecies interaction by means of Feshbach resonances allows us to investigate elusive few-particle cluster states, as well as exotic superfluid and magnetic many-body regimes of highly-correlated fermionic matter.
