A degenerate quantum gas mixture of erbium and lithium atoms
ORAL
Abstract
Quantum gas mixtures are powerful systems with which to explore few-body and many-body phenomena. We present a platform for the creation of a degenerate quantum gas mixture of erbium and lithium atoms. This mixture features the free choice of quantum statistics via isotope selection, convenient intra- and interspecies Feshbach resonances, strong dipolar interactions, and large mass imbalance. We image the atoms via a high-NA objective. These experimental handles allow us to engineer novel states of matter and study a wide range of phenomena, including atom-resolved impurity physics, spontaneous pattern formation, and the miscible–immiscible phase transition.
