چکیده
Article history: Received 27 May 2013 In final form 19 August 2013 Available online 24 August 2013 Calculations of rotationally inelastic scattering at thermal energies for a model atom–diatom system have been performed using two completely different methodologies. The first method is the multi-configuration time-dependent Hartree (MCTDH) wave packet method, and the second is the well known, timeindependent, Arthurs and Dalgarno coupled channel formalism. Excellent agreement is obtained between the two calculations. The advantages and drawbacks of these two methods are somewhat complementary, so that the decision to use one or the other approach will depend on what type of computational results are desired. 2013 Elsevier B.V.

Calculation of state-to-state cross sections for triatomic reaction by the multi-configuration time-dependent Hartree method.
A framework for quantum state-to-state integral and differential cross sections of triatomic reactive scattering using the Multi-Configuration Time-Dependent Hartree (MCTDH) method is introduced, where a modified version of the Heidelberg MCTDH package is applied. Parity of the system is adopted using only non-negative helicity quantum numbers, which reduces the basis set size of the single par...
متن کاملAn Error Analysis of the Multi-configuration Time-dependent Hartree Method of Quantum Dynamics
This paper gives an error analysis of the multi-configuration time-dependent Hartree (MCTDH) method for the approximation of multi-particle time-dependent Schrödinger equations. The MCTDH method approximates the multivariate wave function by a linear combination of products of univariate functions and replaces the high-dimensional linear Schrödinger equation by a coupled system of ordinary diff...
متن کاملNumerical Simulation of Non-Newtonian Inelastic Flows in Channel based on Artificial Compressibility Method
In this study, inelastic constitutive modelling is considered for the simulation of shear-thinning fluids through a circular channel. Numerical solutions are presented for power-law inelastic model, considering axisymmetric Poiseuille flow through a channel. The numerical simulation of such fluid is performed by using the Galerkin finite element approach based on artificial compression method (...
متن کاملMultilayer multiconfiguration time-dependent Hartree method: implementation and applications to a Henon-Heiles hamiltonian and to pyrazine.
The multilayer multiconfiguration time-dependent Hartree (ML-MCTDH) method is discussed and a fully general implementation for any number of layers based on the recursive ML-MCTDH algorithm given by Manthe [J. Chem. Phys. 128, 164116 (2008)] is presented. The method is applied first to a generalized Henon-Heiles (HH) hamiltonian. For 6D HH the overhead of ML-MCTDH makes the method slower than M...
متن کاملRegularity of the Multi-configuration Time-dependent Hartree Approximation in Quantum Molecular Dynamics
We discuss the multi-configuration time-dependent Hartree (MCTDH) method for the approximation of the time-dependent Schrödinger equation in quantum molecular dynamics. This method approximates the high-dimensional wave function by a linear combination of products of functions depending only on a single degree of freedom. The equations of motion, obtained via the Dirac–Frenkel time-dependent va...
