Nonlinear QED in an ultrastrong rotating electric field: Signatures of the momentum-dependent effective mass
The electron effective mass in a rotating electric field (REF) and its signatures in the nonlinear Breit-Wheeler and nonlinear Compton processes are investigated, recognizing this field as a model for the antinodes of counterpropagating laser beams. In contrast to the case of a plane-wave laser fiel...
