A review is given on the multiconfiguration time-dependent Hartree (MCTDH) method, which
is an algorithm for propagating wavepackets. The formal derivation, numerical …

▪ Abstract This review discusses recent quantum scattering calculations on bimolecular
chemical reactions in the gas phase. This theory provides detailed and accurate predictions …

Describes the chaos apparent in simple mechanical systems with the goal of elucidating the
connections between classical and quantum mechanics. It develops the relevant ideas of …

I. Introduction Chemical change is brought about by the motion of electrons and nuclei within
reactingmolecules. The description of this internal motion is the subject of molecular …

Photodissociation induced by the absorption of single photons permits the detailed study of
molecular dynamics such as the breaking of bonds, internal energy transfer and …

Artificial neural networks are universal function approximators. They can forecast dynamics,
but they may need impractically many neurons to do so, especially if the dynamics is chaotic …

Experiments aimed at understanding ultrafast molecular processes are now routine, and the
notion that external laser fields can constitute an additional reagent is also well established …

A spectral method previously developed for solving the time-dependent Schrödinger
equation in Cartesian coordinates is generalized to spherical polar coordinates. The …

Various methods using fast Fourier transform algorithms or other ''grid''methods for solving
the time‐dependent Schrödinger equation are very efficient if the wave function remains …

In the semiclassical limit, quantum mechanics shows differences between classically
integrable abd chaotic systems. Here we review recent developments in this field. Topics …
