The drag force on ions moving in a magnetized electron plasma is calculated in dielectric linear response. Various representations of the dielectric function e(k, ω) are investigated for their suitability to display the limits for an infinite and a

Electron cooling is a well-established method to improve the phase space quality of ion beams in storage rings. More recently antiprotons have been cooled in traps, first by electrons and then by positrons in order to produce antihydrogen atoms as si

Previously unaccessible plasma states of matter can be produced by irradiation with powerful lasers. The interactions within the plasma shift and distort the spectral lines corresponding to radiative transitions. The shape of the spectra is determine

In this paper the energy loss of a heavy ion moving in a magnetized quantum electron plasma is considered within the linear response and binary collision treatments. Treating the electron-ion interaction force as a small perturbation to the electron

Electron cooling is a well-established method to improve the phase space quality of ion beams in storage rings. In the common rest frame of the ion and the electron beam the ion is subjected to a drag force and it experiences a loss or a gain of ener

Recent shock-wave experiments with deuterium [1, 2] in a regime where a plasma phase-transition has been predicted [3] and their theoretical interpretation are the matter of a controversial discussion (see e.g. [4–8]). In this paper, we apply 'wave

Electron cooling is a well-established method to improve the phase space quality of ion in traps and storage rings. A calculation of this process is complicated as the electron velocity distribution is often anisotropic and the cooling process takes

Experiments on ion–electron recombination in electron coolers show an enhancement of the recombination rate with respect to the standard theory. The theoretical explanation of this effect is an active field of research. Here a parameter-free model

With the aid of Wave Packet Molecular Dynamics (WPMD) simulations we investigate hydrogen under extreme conditions. In this model the protons are treated as classical point-particles, whereas the electrons follow a pseudo-hamiltonian dynamics. For th
