Query: Correlation functions and pressure of non-isothermal plasma   Expressions for correlation functions of classical non-isothermal
two-component plasma are derived. In the limiting case of $\Theta_e\gg\Theta_i$
strong correlations arise due to the existence of weakly damping waves (ionic
sound), whose phase velocity is between the thermal velocities of particles,
$u_e\gg\omega/k\gg u_i$. Owing to these correlations, the additional term in
the expression for pressure due to the Coulomb interaction changes its sign as
compared to the case of thermodynamic equilibrium where such waves do not
exist.
