Electric field in intermediate-energy central HIC
GIF animations of the spacetime evolution of the electric field produced in central collisions of gold ions at intermediate energies sNN=O(310GeV). For more details, see 2402.17136.

Note that (1) the beam direction is taken along the z-axis; (2) F:=E2B2 is the electromagnetic Lorentz invariant; (3) the magnetic field is almost vanishing at the central events and so FE2; and (4) the event average is already taken, which is why we don't see local fluctuations in the animations.
