Two methods for the numerical integration of the time-dependent Schrodinger equation with given initial conditions (initial wave packet) are presented. The first method (method A) is based on the Schrodinger representation of the quantum-dynamical system while the second one (method B) is based upon the intermediate representation. In both cases the quantum dynamical equation is transformed into a system of Hamilton-Jacobi type equations of motion as occurring in multi particle classical dynamics, i.e. standard molecular dynamics techniques can be applied for the integration. The dynamics of a minimum uncertainty Gaussian wave packet in a strongly anharmonic oscillator is taken as an example.

HAMILTON-JACOBI DYNAMICS FOR THE SOLUTION OF TIME-DEPENDENT QUANTUM PROBLEMS .2. WAVE-PACKET PROPAGATION IN 2-DIMENSIONAL, NONLINEARLY COUPLED OSCILLATORS - EXACT AND TIME-DEPENDENT SCF-SOLUTIONS
GUNKEL, T; BAR, HJ; ENGEL, M; YURTSEVER, E; BRICKMANN, J (1994-12-01)
Methods for the approximate numerical integration of the time dependent Schrodinger equation with given initial conditions (the initial wave packet) are presented. The methods are based on the Schrodinger representation of the quantum dynamic system. The quantum dynamic equations are transformed into Hamilton-Jacobi type equations of motion as they occur in multi particle classical dynamics, i.e. standard techniques in molecular dynamics can be applied for the integration. The dynamics of minimum uncerta...
Two-way Fourier Split Step Algorithm over Variable Terrain with Narrow and Wide Angle Propagators
Ozgun, Ozlem; Apaydin, Gökhan; Kuzuoğlu, Mustafa; Sevgi, Levent (2010-07-17)
Helmholtz's wave equation can be approximated by means of two differential equations, corresponding to forward and backward propagating waves each of which is in parabolic wave equation (PWE) form. The standard PWE is very suitable for marching-type numerical solutions. The one-way Fourier split-step parabolic equation algorithm (SSPE) is highly effective in modeling electromagnetic (EM) wave propagation above the Earth's irregular surface through inhomogeneous atmosphere. The two drawbacks of the standard ...
Improved analytical approximation to arbitrary l-state solutions of the Schrodinger equation for the hyperbolical potential
IKHDAİR, SAMEER; Sever, Ramazan (2009-04-01)
A new approximation scheme to the centrifugal term is proposed to obtain the l not equal 0 bound-state solutions of the Schrodinger equation for an exponential-type potential in the framework of the hypergeometric method. The corresponding normalized wave functions are also found in terms of the Jacobi polynomials. To show the accuracy of the new proposed approximation scheme, we calculate the energy eigenvalues numerically for arbitrary quantum numbers n and l with two different values of the potential par...
Oscillation of higher order nonlinear dynamic equations on time scales
Grace, Said R; Agarwal, Ravi P; Zafer, Ağacık (Springer Science and Business Media LLC, 2012-5-23)
Some new criteria for the oscillation of nth order nonlinear dynamic equations of the form x(Delta n) (t) + q (t) (x(sigma) (xi (t)))(lambda) = 0 are established in delay xi(t) a parts per thousand currency sign t and non-delay xi(t) = t cases, where n a parts per thousand yen 2 is a positive integer, lambda is the ratio of positive odd integers. Many of the results are new for the corresponding higher order difference equations and differential equations are as special cases.
Obtaining of Time Response from Frequency Response of Fractional Order Systems
Avsar, Selman Fatih; HAMAMCI, SERDAR ETHEM (2015-05-19)
In this paper, an approximation method for obtaining the unit step response of a fractional order system is presented. The method is based on using piecewise linear equivalence of real frequency response curve of the system. Simulation examples shows that this method gives successful unit step response results for the fractional order systems.
