Coherently Enhanced Cherenkov Radiation by Highly Relativistic and Ultra-Compact Electron Beams
S. Kim, C. Müller, A. B. Voitkiv
Cherenkov radiation is emitted when charged particles penetrate dielectric media with velocity higher than the speed of light in the medium. Recent developments in plasma-based acc…

Comparative study of nonperturbative electron-positron pair production by intense laser fields colliding with either bremsstrahlung -rays or relativistic ions
S. Remme, A. B. Voitkiv, S. Villalba-Chávez +1
It is well known that electron-positron pairs can be created in the strong-field environments formed by (i) a high-intensity laser field and a high-energy -photon (nonlinear Bre…
