  The formation of binary correlations in plasma is studied from the quantum
kinetic equation. It is shown that this formation is much faster than
dissipation due to collisions. In a hot (dense) plasma the correlations are
formed on the scale of inverse plasma frequency (Fermi energy). We derive
analytical formulae for the time dependency of the potential energy which
measures the extent of correlations. We discuss the dynamical formation of
screening and compare with the statical screened result. Comparisons are made
with molecular dynamic simulations.
