BACKGROUND
St John's Wort (hypericum perforatum) is an herbal medicine that is frequently used for therapy of mild depression. Recently, St John's Wort was reported to substantially decrease… (More)

We consider the asymptotic evolution of a relativistic spin-1 2 particle. i.e. a particle whose wavefunction satisfies the Dirac equation with external static potential. We prove that the probability… (More)

The flux-across-surfaces theorem (FAST) describes the outgoing asymptotics of the quantum flux density of a scattering state. The FAST has been proven for potential scattering under conditions on the… (More)

We construct the time evolution for the second quantized Dirac equation subject to a smooth and compactly supported, time dependent, electrodynamic four-vector field. Earlier works on this (e.g.… (More)

Stochastic differential equations in Hilbert space as random nonlinear modified Schrödinger equations have achieved great attention in recent years; of particular interest is the long time behavior… (More)

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 of… (More)

We review the foundations of the scattering formalism for one-particle potential scattering and discuss the generalisation to the simplest case of many noninteracting particles. We point out that the… (More)

We consider the asymptotic evolution of a relativistic spin-1 2 particle. i.e. a particle whose wavefunction satisfies the Dirac equation with external static potential. We prove that the probability… (More)

We show that the particle motion in Bohmian mechanics as the solution of an ordinary differential equation exists globally, i.e., the singularities of the velocity field and infinity will not be… (More)
