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.

Absorption images of two immiscible K and Rb condensates repelling each other (left column). The density profiles of the two condensates are well described by numerical solutions of the nonlinear Schroedinger equations (right column).

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.
