Dynamical Sauter-Schwinger pair creation process from Feynman perspective: Comparison of boundary- and initial-value approaches
J. Z. Kamiński, A. Bechler, M. M. Majczak +1
We investigate the dynamical Sauter-Schwinger pair creation process from the vacuum by an electromagnetic background field using two alternative approaches. The first one is based…

Spirals, vortices, and helicity entanglements in dynamical Sauter-Schwinger pair creation
M. M. Majczak, K. Krajewska, A. Bechler +1
We study helicity correlations of electron-positron pairs created by a homogeneous time-dependent electric field in the Sauter-Schwinger scenario. Our analysis is based on solving…

Scattering matrix approach to dynamical Sauter-Schwinger process: Spin- and helicity-resolved momentum distributions
M. M. Majczak, K. Krajewska, J. Z. Kamiński +1
Dynamical Sauter-Schwinger mechanism of electron-positron pair creation by a time-dependent electric field pulses is considered using the -matrix approach and reduction formulas…
