We have measured the parity-violating electroweak asymmetry in the elastic scattering of
polarized electrons from protons. Significant contributions to this asymmetry could arise from …

Very simply unitary cellular automata on a cubic lattice are introduced to model a discretized
time evolution of the wave functions for spinning particles. In each evolution step the …

The main part of the code presented in this work represents an implementation of the split-
operator method [JA Fleck, JR Morris, MD Feit, Appl. Phys. 10 (1976) 129–160; R. Heather …

The purpose of this paper is to explain the discrepancies existing in the literature relative to
e+ e− pair production in peripheral heavy ion collisions at ultra-relativistic energies. A …

Atomic collisions offer some unique opportunities to study atomic structure and reaction
mechanisms in experiment and theory, especially for projectiles of high atomic number …

We perform a gauge transformation on the time-dependent Dirac equation describing the
evolution of an electron in a heavy-ion collision to remove the explicit dependence on the …

The time-dependent Dirac equation was solved for zero-impact-parameter bare UU
collisions in the monopole approximation using a mapped Fourier grid matrix …

A numerical method for the solution of the time-dependent Dirac equation to describe atomic
processes in relativistic heavy-ion collisions is presented. Different from previous …

Using a B-spline expansion in momentum space, we have solved the time-dependent Dirac
equation numerically for a model, one-dimensional atom which is subjected to an ultra …
