报告摘要:  

In this report, I will summarize the work I have conducted at Purdue University and Kansas State University. Our group at Purdue focuses on theoretical studies of ultracold quantum gases, with an emphasis on universal few-body collisional physics, such as the formation of Feshbach dimers and Efimov trimers. At Kansas State, our lab uses femtosecond laser pulses to investigate the ultrafast photochemical reaction dynamics. We employ a technique called Coulomb explosion imaging to reveal transient molecular structures during chemical reactions. In this report, I will discuss the control of cold atom collisions using external electromagnetic fields, as well as the molecular dynamics simulations to support Coulomb explosion experiments aimed at studying the photochemistry of halomethanes.
