DESCRIPTION: ABSTRACT: In non-linear electromagnetism charges come equippe
 d with a natural screening mechanism a la K-mouflage. In this talk I will 
 briefly review this mechanism and discuss some phenomenological consequenc
 es of a model of dark matter interacting via dark photons. I will then dis
 cuss the linear response of screened charges in the context of Born-Infeld
  and ModMax theories. I will show how it is possible to construct ladder o
 perators for the perturbations and how polarisability and susceptibility o
 f certain series of multiples vanish in the Born-Infeld case. Finally\, I 
 will discuss how perturbation equations correspond to a supersymmetric qua
 ntum mechanical system.
