The recurrance relation method is employed to determine the dynamic structure factor for the single harmonic oscillator and a linear chain of harmonic oscillators. Approximative schemes based on this approach are proposed. Comparison is made with exactly known results.
The dynamics of a 1-d cubic oscillator having a time-dependent harmonic force constant is studied numerically by invoking the time-dependent Fourier grid Hamiltonian method. The temporal variation in K t causes the tunneling rate constant to decrease or increase, depending upon the nature of the tim
A generalized master equation is derived for a Morse oscillator coupled to a bath of harmonic oscilIa:ors\_ Manipulation involving the Morse os@lator is facilitated by the use of an SU(2) algebra, and calculations related to the harmonic oseiIlators by using the ladder oper+ors. The temporal evoluti
