Relaxation of plasma waves in Fermi-degenerate quantum plasmas

Autor: H.-J. Kull, Wibke Steffen

Publikováno v: Physical Review E. 93

Plasma waves in a Fermi-degenerate quantum plasma are studied in the framework of the Vlasov-Poisson self-consistent-field theory. A complete time-dependent analytical solution of the initial-value problem is obtained for a multistream model both by

Numerical calculation of strong-field laser-atom interaction: An approach with perfect reflection-free radiation boundary conditions

Autor: Marco Heinen, H.-J. Kull

Publikováno v: Laser physics 20, 581-590 (2010). doi:10.1134/S1054660X10050063

The time-dependent, single-particle Schrodinger equation with a finite-range potential is solved numerically on a three-dimensional spherical domain. In order to correctly account for outgoing waves, perfect reflection-free radiation boundary conditi

Wigner representation of ionization and scattering in strong laser fields

Autor: C. Baumann, H.-J. Kull, G. M. Fraiman

Publikováno v: Physical Review A. 92

The interaction of single-electron atoms with a strong laser field is studied in the Wigner representation. The Wigner function is a quasiprobability function in phase space that allows one to study position-momentum correlations. These correlations

Two-dimensional PIC simulation of atomic clusters in intense laser fields

Autor: F. Greschik, H.-J. Kull

Publikováno v: Laser and Particle Beams. 22:137-145

Collective absorption of intense laser pulses by atomic clusters is studied by PIC simulations. The cluster is modeled in two-dimensional calculations as a cylindrical plasma column with a diameter of D = 6.4 nm and an initial electron density of ne0
