The time-dependent Dirac equation was solved for zero-impact-parameter bare U-U collisions in the monopole approximation using a mapped Fourier grid matrix representation. A total of 2048 states including bound, as well as positive- and negative-energy states for an $N=1024$ spatial grid were propagated to generate occupation amplitudes as a function of internuclear separation. From these amplitudes spectra were calculated for total inclusive positron and electron production, and also the… Expand

How to Observe the Vacuum Decay in Low-Energy Heavy-Ion Collisions.
TLDR
It is shown that the vacuum decay can nevertheless be observed via impact-sensitive measurements of pair-production probabilities and the possibility of such an observation is demonstrated using numerical calculations of pair production in low-energy collisions of heavy nuclei. Expand

TLDR
Positron creation in crossed-beam collisions of high-energy, fully stripped heavy ions is investigated within the coupled-channel formalism and the positron spectrum is shifted towards higher energies because of the absence of electron screening. Expand
