Title:Polyexciton stability in multi-valley semiconductor and optical trap for valley exciton

Professional development Consortium for Computational Materials Scientists (PCoMS) is the organization established to develop human resources of computational material science. I participated the internship program of PCoMS and stayed in prof. Varga’s group in the Vanderbilt University for almost 1 month in this spring. In this stay. My activity was focused on settling the current research project and putting the next research issue into shape. Current project is the identification of polyexciton stability in multi-band semiconductor and verified up to triexciton bound states by numerical calculation. Next research issue is assessing the feasibility of optical trap for 2D exciton by utilizing optical Stark effect. I will report the details and contributions of the internship to my research.
