Dynamics of cubic-quintic nonlinear Schrödingeröequation are studied numerically with symplectic method. Behaviors of the equation are discussed with increased quintic nonlinear parameter. We observe homoclinic orbit crossing and elliptic orbit in turn and the system has recurrent solutions. Pattern drifting of solutions is also discussed. It is shown that pattern drifting can be slowed down by increasing the quintic nonlinear parameter.

Classical Dynamics of a Hydrogen Molecular Ion (H₂⁺) Intense Laser Fields:1D and 3D Models

GUO Jing, LIU Shixing, XU Tianfu, LIU Xueshen, DING Peizhu

CHINESE JOURNAL OF COMPUTATIONAL PHYSICS 2008, 25 (4): 470-476.

Classical trajectory method is used in 1D and 3D models to study classical dynamics of Hydrogen molecular ion (H₂⁺) in intense laser fields. Probabilities of survival, ionization, dissociation and Coulomb explosion and average distance between electron and the mass-center are calculated. It is shown that the 1D model is available for dynamics of hydrogen molecular ion in intense laser fields.
