Space-charge-based electrostatic plasma confinement involving relaxed plasma species (open access)

Space-charge-based electrostatic plasma confinement involving relaxed plasma species

In this article, a numerical study is reported on the equilibrium properties of a surface-emitted or edge-confined non-drifting plasma. A self-consistent finite-differences evaluation of the electrostatic potential is carried out for a non-neutral plasma that follows a Boltzmann density distribution.

Artificially structured boundary for confinement of effectively unmagnetized cryogenic antimatter plasmas (open access)

Artificially structured boundary for confinement of effectively unmagnetized cryogenic antimatter plasmas

The article is from conference proceedings that discuss an artificially structured boundary (ABS) considered to consist of a spatially periodic arrangement of electrostatically plugged magnetic cusps. As envisioned, a non-neutral positron plasma could be confined by an ASB along its edge, and the space charge of the positron plasma would serve to confine an antiproton plasma. If the conditions of the two-species plasma are suitable, production of antihydrogen via three-body recombination for antimatter gravity studies may be possible.

Temporal complexity measure of reaction time series: Operational versus event time (open access)

Temporal complexity measure of reaction time series: Operational versus event time

Article describes how detrended fluctuation analysis (DFA) is a well-established method to evaluate scaling indices of time series, which categorize the dynamics of complex systems. The authors propose treating each reaction time as a duration time that changes the representation from operational (trial number) time n to event (temporal) time t, or X(t).

Relaxation time approximations in PAOFLOW 2.0 (open access)

Relaxation time approximations in PAOFLOW 2.0

Article presents the implementation of relaxation time approximation models in the calculation of Boltzmann transport in PAOFLOW 2.0 and applies those to model band-structures. In addition, using a self-consistent fitting of the model parameters to experimental conductivity data, the authors provide a flexible tool to extract scattering rates with high accuracy. They illustrate the approximations using simple models and then apply the method to GaAs, Si, Mg₃Sb₂, and CoSb₃.
