Carrollian Born-Infeld Electrodynamics

I will discuss the Born-Infeld (BI) Electrodynamics in its Carrollian limit
and show that it differs significantly from its conformal Carrollian
cousin. For example, the full conformal Carroll symmetry group is broken
due to the presence of nonlinear interactions among U(1) gauge fields.
Moreover, these theories do not allow for an underlying Lagrangian
description, which is also an artefact of quartic interactions among U(1)
gauge fields. Most interestingly, the two point correlation depends upon
the square of the distance of separation between two spatial points and
does not exhibit the usual power law behaviour as in the case of conformal
Carrollian Electrodynamics. We identify this as an artefact of the broken
dilation invariance in the Carrollian limit of BI Electrodynamics.
