Abstract: Title:Short pulse generation with ionization
Lei Yang
Abstract:Ultra-short laser pulse can be generated by ionization process of neutral gas, which cut off the long laser pump pulse into short one after dense plasma is generated. Physical picture and paramter dependencies are discussed using 3D PIC code.
Title: Dynamic processes of 3D magnetic reconnection with external shear flows
Lingjie Li
Abstract: Influences of shear flows on the nonlinear evolution of the magnetic reconnection are studied in the framework of 3D compressible resistive MHD. The initial condition both with and without the Earth dipole are considered in the simulation model. Also, the interaction of the solar wind with the Earth’s magnetosphere and the basic concepts of magnetic reconnection and shear flows are included in this talk.
