  In the instanton ensemble the fermionic zero modes collectivize and break
chiral symmetry. Recent studies of resulting zero mode zone confirm its very
small width and overall importance for lattice simulations.
  Confinement however has been related with completely different topological
objects, the magnetic monopoles. Instanton constituents -- instanton dyons,
discovered at nonzero holonomy by Pierre van Baal and others -- are able to
explain both confinement and chiral symmetry breaking. The talk summarizes
recent works deriving the instanton-dyon mutual interactions, and statistical
studies of their ensemble. At high density the screening is robust enough to do
it analytically, in the mean-field-type approach: we call this limit Dense
Dyonic Plasma (DDP). Above $T_c$ the classical interaction between the dyons
induce strong correlations and should be studied by direct numerical
simulations. Those works are now in progress.
