Development of a high-repetition-rate modular Bose-Einstein condensates source for Quantum Technologies

当稀释的玻色子气体被冷却到如此低的温度，以至于单个原子的热德布罗意波长变得如此之大以至于重叠时，就会发生玻色子-爱因斯坦凝聚（BEC）的相变。这种现象将整个气体视为一个单一的宏观量子物体，这是一个值得研究的非凡模型系统，并为凝聚态物理领域提供了新的见解。我们的实验重点是研究铷原子玻色-爱因斯坦凝聚体被困在所谓的原子芯片表面。

The phase transition to Bose-Einstein condensation (BEC) occurs when a dilute gas of bosons is cooled to such low temperatures that the thermal de Broglie wavelengths of the individual atoms grow so large as to overlap. This phenomenon sees the entire gas behaving as a single, macroscopic quantum object, which is a remarkable model system to study, and has provided new insights into the field of condensed matter physics.Our experiment is focused on studies of atomic rubidium Bose-Einstein condensates trapped on the surface of a so-called atom chip.
