Spin resolved momentum spectra for vacuum pair production via a generalized two level model
Orkash Amat, Hong-Hao Fan, Suo Tang +2
We have formulated a generalized two level model for studying the pair production in multidimensional time-dependent electric fields. It can provide momentum spectra with fully spi…

Spin Effect induced Momentum Spiral and Asymmetry Degree in Pair Production
Li-Na Hu, Hong-Hao Fan, Orkash Amat +2
Spin effect on the pair production under circularly polarized fields are investigated. Significantly different from what momentum spirals caused by two counter-rotating fields with…

Asymmetric pulse effects on pair production in chirped electric fields
Neng-Zhi Chen, Orkash Amat, Li-Na Hu +2
We investigate the effects of the asymmetric pulse shapes on electron-positron pair production in three distinct fields: chirp-free, small frequency chirp, and large frequency chir…
