It is shown that the addition of a non-linear term to the Lagrangian of the electromagnetic field yields a fluid with an asymptotically super-negative equation of state, causing an accelerated expansion of the universe. Some general properties of nonlinear electromagnetism in cosmology are also discussed.

Introductory Notes on Non‐linear Electrodynamics and its Applications (2021, background): “As was shown in [85] this may occur, for instance, if the universe is dominated by non-linear electromagnetic fields described by the following non-linear Lagrangian density”
Analogue Gravity (2005, methodology): “What the “analogue gravity programme” does not seem to do as easily is to provide a natural direct route to the Einstein equations of general relativity, but that merely indicates that current analogies have their limits and therefore, one should not take them too literally [378,283].”
Could dark energy be vector-like? (2004, background): “Also, it has been noted that the addition of higher-order powers of the Maxwell field-strength to the Lagrangian of an electromagnetic field might cause the universe to accelerate [28].”
