Intrinsic Nonlocality of Spin- and Polarization-Resolved Probabilities in Strong-Field Quantum Electrodynamics
Samuele Montefiori, Antonino Di Piazza, Tobias Podszus +2
Spin and polarization are central to precision tests of fundamental physics and for interpreting radiation from astrophysical sources and ultraintense laser-matter experiments. Her…

Nonlinear Compton scattering and nonlinear Breit-Wheeler pair production including the damping of particle states
Tobias Podszus, Victor Dinu, Antonino Di Piazza
In the presence of an electromagnetic background plane-wave field, electron, positron, and photon states are not stable, because electrons and positrons emit photons and photons de…
