Extended Data Fig. 1: Theoretical calculations of the electric field around a negative point charge under the Lorentz transformation.
From: Ultrafast visualization of an electric field under the Lorentz transformation
a,b, 2D electric field profiles around a negatively charged particle with energies of 0 and 35 MeV, respectively. Here, the absolute electric field strength is shown by the color bar and the direction is denoted by the black vectors.
