Within the framework of Lanczos-inspired perturbation theory wave functions and energies in the short-range potential V (x) = a ρ 2 (x) + λ ρ 4 (x) with ρ(x) = sech αx and a small coupling λ are shown obtainable in closed form.

1 Email: [email protected] Abstract. This paper presents the research undertaken to produce a robotic story-teller. Based in the field of narrative intelligence, the aim is to produce a behaviour-based control architecture for an autonomous mobile robot which allows the robot to dynamically construct its autobiography and relate it to others in terms of a story expressed through behaviou...

The Jahn-Teller (JT) theorem states that in a molecule with a degenerate electronic state, a structural distortion must occur that lowers the symmetry, removes the degeneracy and lowers the energy. The multideterminental-DFT method performed to calculate the JT parameters for JT active molecules is described. Within the harmonic approximation the JT distortion can be analyzed as a linear combin...
