Quantum Mixtures




We look into the micro-world of ultracold atoms: our dual-species Bose-Einstein condensates are a few micrometers in size and have a temperature of less than a millionth of degree above absolute zero. We shield these fragile and delicate creatures from the hostile outside world by imprisonment in high-vacuum chambers.

Description

Mixtures of quantum gases provide ideal platforms for simulating multi-component quantum systems, where mutual interactions between components give rise to quantum effects that are unattainable in their single-component counterparts.
In our lab, we exploit ultracold mixtures of K and Rb with tunable interspecies interactions to investigate multi-component superfluidity; novel states of quantum matter, such as quantum droplets and LHY fluids; phase transitions and criticality; impurity physics; and many-body entanglement.
