EPJ B – A step up in the game of electron-ion dynamics simulations

A Colloquium paper by McEniry et al. published in EPJ B surveys the theory and applications of a new family of computational methods, namely Correlated Electron-Ion Dynamics, which enable the simultaneous evaluation of the electronic current, along with the current-induced forces and subsequent motion of the nuclei.

EPJ H - Foundations of Quantum Statistical Physics Revisited

There is a divide, in quantum statistical physics, between the "ensemblists" who regard thermal equilibrium as a property of an ensemble (or a mixed state) and the "individualists" who regard thermal equilibrium as a property of an individual system (in a pure state). A long forgotten concept of equilibrium put forward by John von Neumann in 1929 is reanalyzed and shown to be influenced by both approaches, yet to be mainly based on the individualist view - a view that has gained ground recently.

EPJ D - Ions that love DNA to bits

Ions that love DNA to bits

Low energy carbon ions have been directed to small DNA strand. The results provide new information of the mechanisms of DNA damage during ion beam therapy, also called hadron therapy.

EPJ D – Measurements in the hot spot of a plasma

Measurements in the hot spot of a plasma

A group of researchers in Greifswald, Germany, measured the electron concentration and electron temperature in the active discharge zone of a self-organized plasma jet. Self-organized discharge patterns are shown as time averaged top view in the picture.

Miniaturized non-thermal plasma jets are an emerging technique for surface treatments at ambient pressure, such as cleaning, activation, etching, films deposition and more.

The authors of this EPJ D paper used two independent approaches: spectroscopy and a two-dimensional fluid model calculation of a discharge filament. The results from the two methods are consistent and indicate electron concentrations between 2.2 and 3.3×1014 cm-3. This work represents a first step towards a thorough physical description of the discharge dynamics and energy transport to gain a better understanding of self-organization effects in non thermal plasma jets.

Geysers of Helium burst as if liquid

Geysers of Helium burst as if liquid

New experiments on the flow of solid He through a microscopic hole reveal a mechanism that triggers the geysers based on the breakdown of a plug located upstream of the source chamber.

The vacuum expansion of solid helium through a micrometric orifice was suggested as a mean to inject excess vacancies into the solid bulk [R. Grisenti et al, J. Electr. Spectr. 129 (2003) 201]. But while the He flow seems smooth, unexpected periodic bursts out of the orifice (geyser effect) are observed during these vacuum expansion experiments.
