摘要:
Ultracold molecular gas provides a promising platform for investigation of quantum information and quantum simulation. The lifetime of the ultracold molecular gas is limited since the loss rate due to molecular collision is large. As a result, it is important to understand the collision between two ultracold molecules. In this talk, a simple model for ultracold molecular collisions is presented. Based on the model, the effect of the quantum reflection and coherence on the loss rate is revealed. Finally, the model is adopted to extract scattering parameters from the experimental results.
