Research of atomic and molecular physics under extreme conditions is an important direction of physics study in 21st century,which are of great scientific significance but also  can push forward the national strategic high technology and the related interdisciplinary research. Our group focus on the research of cold atomic physics, ultraclold neutral plasma  and the interaction of matter with a strong laser field. Such investigation are not only a fundamental problem of atomic and molecular physics, plasma physics and  condensed matter physics and quantum information sciences,  , but also have comprehensive applications in inertial-confinement fusion ,and  new energy weapon physics, etc.
