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…
