Preface v Mixed Quantum/Classical Dynamics: Bohmian and DVR Stochastic Trajectories C. Meier, J. A. Beswick, T. Yefsah 1 Trajectory-Based Derivation of Classical and Quantum Mechanics We describe the advantages and disadvantages of numerical methods when Bohmian trajectory-grids are used for numerical simulations of quantum dynamics. We focus on the crucial non crossing property of Bohmian trajectories, which numerically must be paid careful attention to. Failure to do so causes instabilities or leads to false simulations.

The quantum potential introduces all quantum features into the dynamics, including interference effects, barrier tunneling, zero point energies, etc. The only approximation made in solving the hydrodynamic equations involves the use of a relatively small number of fluid elements. The equations of motion for these fluid elements are expressed in the moving with the fluid, Lagrangian Quantum dynamics with stochasticgauge simulations Table 1.

An approach to electron correlation effects in atoms that uses quantum trajectories is presented. A comparison with the exact quantum mechanical results for 1D Helium atom shows that the major features of the correlated ground state distribution and of the strong field ionization dynamics are reproduced with quantum trajectories.

Quantum Dynamics with Bohmian Trajectories. we describe the advantages and disadvantages of numerical methods when bohmian trajectory grids are used for numerical simulations of quantum dynamics. we focus on the crucial noncrossing property, the trajectories are either transmitted to the reactant region or reflected back into the product region in a course of the dynamics under the influence of a classical and quantum potentials. the transmission probability is a sum over trajectories in the product region p =∑ ′ i w ( i ) at time t max when the bifurcation of the wavepacket is complete (completed in 180 steps at t max =1.8).).
