Nonperturbative Time Dependent Solution of a Simple Ionization Model
We present a non-perturbative solution of the Schrödinger equation iψt = −ψxx−(2−α sinωt)δ(x)ψ describing the ionization of a model atom by a parametric oscillating potential. This model has been studied extensively by many authors, including us. It has surprisingly many features in common with those observed in the ionization of real atoms and emission by solids, subjected to microwave or lase...
متن کاملNumerical solution of time-dependent foam drainage equation (FDE)
Reduced Differental Transform Method (RDTM), which is one of the useful and effective numerical method, is applied to solve nonlinear time-dependent Foam Drainage Equation (FDE) with different initial conditions. We compare our method with the famous Adomian Decomposition and Laplace Decomposition Methods. The obtained results demonstrated that RDTM is a powerful tool for solving nonlinear part...
متن کاملTime dependent ionization calculations of gaseous nebulae
We developed a new computer code which is able to treat the time dependent photoand collisional ionization of gaseous nebulae together with the consistent energy balance for arbitrary numbers of elements, ions and line transitions. The intention of this paper is to describe the basic numerical methods and a few test calculations as being parts of full spherically symmetric radiation-gasdynamic ...
متن کامل4 Simple Soluble Molecular Ionization Model ∗
We present a simple exact analytical solution, using the Weyl-Titchmarsh-Kodaira spectral theorem, for the spectral function of the one-dimensional diatomic molecule model consisting of two attractive delta function wells in the presence of a static external electric field. For sufficiently deep and far apart wells, this molecule supports both an even and an odd state, and the introduction of a...
متن کاملTime-dependent entropy of simple quantum model systems
Information-theoretic entropy measures are useful tools for quantifying the spreading of quantum states in phase space. In the present paper, we compare the time evolution of the joint entropy for three simple quantum systems: sid a free Gaussian wave packet, siid a wave packet in a monochromatic electromagnetic field, and siiid a wave packet tunneling through a d barrier. As initial condition ...
