We give the energy distributions of electrons and ions supporting a steady state electrostatic structure in a collisionless plasma. The electric potential of the structure is skew asymmetrically distributed in space. We show that the jump discontinuous, logarithmically singular electron and ion distributions may be reduced to elliptic integrals. We give the coefficients of the logarithmic terms and the jumps at the discontinuities and we show that they are reciprocally proportional. We calculate bounds for the potential skew asymmetry and show that these bounds are regulated by the boundary conditions of the particle distributions. Despite singularities, our treatment reproduces a smooth space distribution of the potential amplitude and electron and ion distributions that are smooth at one of the boundaries of the electrostatic structure.

    The results are discussed of a 2½ dimensional, undriven, fully open-boundary particle-in-cell simulation of symmetric, anti-parallel reconnection. It is shown that the reconnection rate as measured by the strength of the out-of-plane electric field component at the dominant x-line is fast and...

    The evolution of the electron energy distribution function is investigated in the low-pressure capacitive discharge under the collisionless electron heating regime, where the electron mean-free path is comparable to or larger than the system length. As the gas pressure decreases from 50 to 10...

    We investigate the equilibrium states of the one-dimensional ion conductor. The consideration is based on the Pauli lattice model that takes into account the ion transfer, interaction between the nearest-neighbouring ions and the modulating field. By using the exact diagonalization method for...

    The classical source-collector sheath system describes a plasma that forms between a Maxwellian source and an absorbing wall. The plasma is assumed to be collisionless and without ionization. Two distinct areas are being formed: the collector sheath, an ion-rich region in contact with the...

    The one-dimensional collisionless expansion into a vacuum of a thin foil is studied with an hybrid code where ions are treated as particles and electrons as a fluid, the two populations being coupled by the Poisson equation. The electrons are assumed to have a Maxwellian distribution function...
