Abstract: The preparation and research of cold molecules have some important scientific significances and wide applied prospects. In this talk, we will first report three methods to prepare cold molecules and their experimental results in ECNU, including Stark velocity filtering, buffer-gas cooling and electrostatic Stark decelerating. Afterwards, we will introduce some techniques to manipulate and control cold molecules and their theoretical and experimental results in ECNU, including controllable high-efficient surface guiding, controllable molecular-beam splitter, electrostatic trap and surface storage ring for cold molecules. Finally, we briefly present our recent research progress of cold molecules, including laser cooling of MgF molecules, high-efficient electrostatic Stark slowing for PbF molecules and pendular spectrum of cold molecules and its applications.
