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…

Orbital magnetoelectric coupling of three dimensional Chern insulators
Xin Lu, Renwen Jiang, Zhongqing Guo +1
Orbital magnetoelectric effect is closely related to the band topology of bulk crystalline insulators. Typical examples include the half quantized Chern-Simons orbital magnetoelect…
