Angular momentum transfer in multiphoton pair production
R. Z. Jiang, Z. L. Li, Y. J. Li
We propose a method to accurately calculate the momentum distributions and the phase distributions of the probability amplitude for both boson and fermion pair production in a spat…
Electron-positron pair creation in a supercritical static asymmetric potential well
Z. L. Li, A. R. Sun, J. H. Xia +2
The electron-positron pair creation in a supercritical static asymmetric potential well, which is composed of a subcritical and a supercritical potential separated by a fixed dista…
Enhancing pair production with optimized chirped laser fields
Z. L. Li, Y. F. Chen, R. Z. Jiang +1
The optimal chirped field for enhancing electron-positron (EP) pair production is explored using a quantum kinetic approach. First, the momentum spectrum and number density of EP p…
Study of spin states in vacuum pair production via the Dirac-Heisenberg-Wigner formalism
R. Z. Jiang, Z. L. Li, Y. J. Li
A general spin-resolved momentum distribution of electron-positron pairs produced in strong external fields is derived by combining the covariant spin projection operator and the D…
Electron-hole pair production in graphene for two arbitrarily polarized electric fields with a time delay
R. Z. Jiang, Z. L. Li, Y. J. Li
The momentum distributions of electron-hole (EH) pair production in graphene for two arbitrarily polarized electric fields with a time delay are investigated employing a massless q…
