In this paper we study the quantum corrections to the Bernstein‐Greene‐Kruskal equilibria of plasma physics by using perturbation methods near the classical solution. We obtain the solution for the Wigner function and for the self‐consistent potential to first order in the smallness parameter, which is the square of Planck's constant (in dimensionless form), and investigate the structure of the quantum phase space.
