  Amorphous solids under mechanical strains are prone to plastic responses.
Recent work showed that in amorphous granular system these plastic events, that
are typically quadrupolar in nature, can screen the elastic response. When the
density of the quadrupoles is high, the gradients of the quadrupole field act
as emergent dipole sources, leading to qualitative changes in the mechanical
response, as seen for example in the displacement field. In this paper we
examine the effect of screening in classical glass formers. These are made of
point particles that interact via binary forces. Both inverse power law forces
and Lennard-Jones interactions are examined, and it is shown that in both cases
the elastic response can be strongly screened, in agreement with the novel
theory. The degree of deviation from classical elasticity theory is
parameterized by a proposed new measure that is shown to have a functional
dependence of on the amount of energy lost to plastic responses.
