Abstract
In this thesis, interaction of light and matter in two dimensional molecular crystal is mainly discussed. The interaction of light and matter is described by time-dependent Schrӧdinger equation. The parameters in time-dependent Schrӧdinger equation are referred from previous experimental and theoretical studies. Fourth-order Runge-Kutta method gives the numerical data of wave function in time-dependent Schrӧdinger equation. We calculated the rubrene single molecule and the crystalline molecular system on a 80×80 sites with periodic boundary condition. In the investigation of single molecule, propagation of molecular polarization is induced by ultrashort laser pulse in the femtosecond region. We find that there exists the robust destructive interference of the polarization between ground and excited state. The single crystal model describes diffusion of excited state and molecular distortion in each molecule. ⓒ 2016 DGIST
