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

\sqrt{s_{N N}} = O (3 - 10 G e V)

. For more details, see 2402.17136.

Note that (1) the beam direction is taken along the

z

-axis; (2)

F := E^{2} - B^{2}

is the electromagnetic Lorentz invariant; (3) the magnetic field is almost vanishing at the central events and so

F \approx E^{2}

; and (4) the event average is already taken, which is why we don't see local fluctuations in the animations.
