Spectral fringes without subcycles in Schwinger pair production and Dirac materials
I. A. Aleksandrov, M. A. Dorodnyi, E. D. Akimkina
Spectral fringes in Schwinger pair creation are usually attributed to structured driving, such as carrier oscillations, pulse trains, or multiple creation events. We show that pron…
Helicity effects in the dynamically assisted Schwinger mechanism
A. I. Baksheev, V. A. Bokhan, A. Kudlis +1
We study vacuum electron-positron pair production in a spatially uniform bichromatic electric field within the quantum-kinetic framework for fermions. The external background model…
Schwinger pair production in counterpropagating laser pulses: Identifying volume factors
A. G. Tkachev, I. A. Aleksandrov, V. M. Shabaev
We investigate the nonperturbative process of vacuum pair production in a combination of two counterpropagating linearly polarized laser pulses of a finite spatial extent. By means…
Vacuum pair production in zeptosecond pulses: Peculiar momentum spectra and striking particle acceleration by bipolar pulses
I. A. Aleksandrov, N. N. Rosanov
We examine the phenomenon of electron-positron pair production from vacuum in a combination of two counterpropagating electromagnetic pulses having a duration of the order of the C…
