Boltzmann approach to the longitudinal spin Seebeck effect
Rico Schmidt, Francis Wilken, Tamara S. Nunner +1
We develop a Boltzmann transport theory of coupled magnon-phonon transport in ferromagnetic insulators. The explicit treatment of the magnon-phonon coupling within the Boltzmann ap…
Impurity-assisted Andreev reflection at a spin-active half-metal-superconductor interface
Francis B. Wilken, Piet W. Brouwer
The Andreev reflection amplitude at a clean interface between a half-metallic ferromagnet (H) and a superconductor (S) for which the half metal's magnetization has a gradient perpe…
Momentum distributions in time-dependent density functional theory: Product phase approximation for non-sequential double ionization in strong laser fields
F. Wilken, D. Bauer
We investigate the possibility to deduce momentum space properties from time-dependent density functional calculations. Electron and ion momentum distributions after double ionizat…
Nonsequential Double Recombination in Intense Laser Fields
P. Koval, F. Wilken, D. Bauer +1
A second plateau in the harmonic spectra of laser-driven two-electron atoms is observed both in the numerical solution of a low-dimensional model helium atom and using an extended…
Adiabatic Approximation of the Correlation Function in the Density-Functional Treatment of Ionization Processes
F. Wilken, D. Bauer
The ionization of a one-dimensional model Helium atom in short laser pulses using time-dependent density functional theory is investigated. We calculate ionization probabilities as…
