New DNLS Equations for Anharmonic Vibrational Impurities
نویسنده
چکیده
We examine some new DNLS-like equations that arise when considering strongly-coupled electron-vibration systems, where the local oscillator potential is anharmonic. In particular, we focus on a single, rather general nonlinear vibrational impurity and determine its bound state(s) and its dynamical selftrapping properties. email: [email protected] PACS number(s): 71.55.-i

A lower bound for the power of periodic solutions of the defocusing Discrete Nonlinear Schrödinger equation
We derive lower bounds on the power of breather solutions ψn(t) = e −iΩtφn, Ω > 0 of a Discrete Nonlinear Schrödinger Equation with cubic or higher order nonlinearity and site-dependent anharmonic parameter, supplemented with Dirichlet boundary conditions. For the case of a defocusing DNLS, one of the lower bounds depends not only on the dimension of the lattice, the lattice spacing, and the fr...
متن کاملCalculating molecular vibrational spectra beyond the harmonic approximation
We present a new approach for calculating anharmonic corrections to vibrational frequency calculations. The vibrational wavefunction is modelled using translated Hermite functions thus allowing anharmonic effects to be incorporated directly into the wavefunction whilst still retaining the simplicity of the Hermite basis. We combine this new method with an optimised finite-difference grid for co...
متن کاملNew parallel software (P_Anhar) for anharmonic vibrational calculations: Application to (CH3Li)2
We present the development of a new parallel computer code (P_Anhar_v1.0) to calculate the vibrational spectrum of medium size molecules using a variational algorithm. The method is applied to the determination of a complete quartic anharmonic force field (B3LYP/cc-pVTZ) for methyllithium, leading to a new interpretation of experimental data.
متن کاملDegenerate perturbation theory corrections for the vibrational self-consistent field approximation: Method and applications
A new algorithm for computing anharmonic vibrational states for polyatomic molecules is proposed. The algorithm starts with the vibrational self-consistent field ~VSCF! method and uses degenerate perturbation theory to correct for effects of correlation between different vibrational modes. The algorithm is developed in a version that computes the anharmonic vibrational spectroscopy directly fro...
متن کاملA variational approach for calculating Franck-Condon factors including mode-mode anharmonic coupling.
We have implemented our new procedure for computing Franck-Condon factors utilizing vibrational configuration interaction based on a vibrational self-consistent field reference. Both Duschinsky rotations and anharmonic three-mode coupling are taken into account. Simulations of the first ionization band of ClO(2) and C(4)H(4)O (furan) using up to quadruple excitations in treating anharmonicity a...
