Multiscale Analysis of a Davydov Model with an Harmonic Long Range Interaction of Kac-Baker Type
Dan Grecu, Anca Visinescu
The classical equation of motion of a Davydov model in a coherent state approximation is analyzed using the multiple scales method. An exponentially decaying long range interaction…

Beyond Nonlinear Schrödinger Equation Approximation for an Anharmonic Chain with Harmonic Long Range Interaction
D. Grecu, Anca Visinescu, A. S. Carstea
Multi scales method is used to analyze a nonlinear differential-difference equation. In order the NLS equation is found to determine the space-time evolution of the leading a…

Long range interaction corrections on the quantum vibronic soliton
D. Grecu, A. S. Cârstea, Anca Visinescu
Self-localized modes in a quantum vibronic system, with long range interaction of Kac-Baker type and interacting nonlinearly with an acoustical phonon bath, is studied. One works i…
