A new method for calculations of electron-positron pair-creation probabilities in low-energy heavy-ion collisions is developed. The approach is based on the propagation of all one-electron states via the numerical solving of the time-dependent Dirac equation in the monopole approximation. The electron wave functions are represented as finite sums of basis functions constructed from B-splines using the dual-kinetic-balance technique. The calculations of the created particle numbers and the…

Electron-positron pair production in slow collisions of heavy nuclei beyond the monopole approximation
Electron-positron pair production in low-energy collisions of heavy nuclei is considered beyond the monopole approximation. The calculation method is based on the numerical solving of the
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.
Pair creation in low-energy collisions of heavy nuclei beyond the monopole approximation
The creation of electron-positron pairs in slow collisions of heavy nuclei is considered beyond the monopole approximation. The nonperturbative calculations of pair-creation probabilities are

The probabilities and cross sections of electron-positron pair creation in low-energy collisions of heavy bare nuclei are calculated. The calculations are performed in the framework of the one-center
Peculiarities of the electron energy spectrum in the Coulomb field of a superheavy nucleus

Plunging in the Dirac sea using graphene quantum dots
The dynamics of low energy charge carriers in a graphene quantum dot subjected to a time-dependent local field is investigated numerically. In particular, we study a configuration where a Coulomb

Abstract.We consider the electromagnetic production of positron in the collision of slow heavy nuclei, with the simultaneously produced electron captured by one of the nuclei. The cross-section of
Electromagnetic production of positrons and electrons in collisions of heavy nuclei
We consider the electromagnetic production of positrons and electrons in collisions of slow heavy nuclei. This process is dominated by emission of positrons, with the electrons captured by nucleus.
