Baslik: Aspects of maximally symmetric non-linear (ModMax) electrodynamics

Ozet: We will review properties and peculiarities of a recently found unique
non-linear generalization of Maxwell's electrodynamics (dubbed ModMax) that
preserves all the symmetries of the former, i.e. conformal invariance and
electric-magnetic duality. In particular, we will see that ModMax admits, as
exact solutions, plane waves and Lienard-Wiechert fields induced by a moving
electric or magnetic particle, or a dyon; effects of ModMax may manifest
themselves in physical phenomena such as vacuum birefringence and in
properties of gravitational objects (e.g. charged black holes). ModMax and
its Born-Infeld-like generalization arise as TTbar-like deformations of
Maxwell's theory and there exist supersymmetric and higher-spin extensions
of these models.

Plan of the seminars (flexible, depends on preferences of the listeners and
time available).

First Part:
0) 90 years of non-linear electrodynamics.
1) Introduction to electric-magnetic duality and conformal symmetry in
Maxwell's and non-linear electrodynamics. Born-Infeld theory.
2) ModMax and its distinguished features.
3) Exact solutions of the ModMax equations of motion (plane waves and
Reissner-Nordstrom black holes).

Second Part:

1) Phenomenon of "vacuum birefringence" in non-linear electrodynamics.
2) What are "TTbar" deformations of field theories and their relation to
the Born-Infeld electrodynamics and ModMax?
3) ModMax as an effective theory of electromagnetic interactions wit an
axion-dilaton-like field.
4) Supersymmetric extension and coupling to supergravity.
