Reconfigurable Surface Plasmon Polariton Wave Adapter Designed by Transformation Optics (open access)

Reconfigurable Surface Plasmon Polariton Wave Adapter Designed by Transformation Optics

This article proposes a reconfigurable surface plasmon polariton (SPP) wave adapter designed by transformation optics, which can control the propagation of SPP waves on un-even surfaces.

Simulation of an aperture-based antihydrogen gravity experiment (open access)

Simulation of an aperture-based antihydrogen gravity experiment

This article presents a Monte Carlo simulation of an experiment that could potentially determine whether antihydrogen accelerates vertically up or down as a result of earth's gravity.

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.

Spatially Periodic Electromagnetic Force Field For Plasma Confinement and Control (open access)

Spatially Periodic Electromagnetic Force Field For Plasma Confinement and Control

In this article, a theoretical understanding is developed of the single-particle reflection properties of a force field, considering the incident charged particles to have a non-drifting, isotropic velocity distribution. Classical trajectory Monte Carlo simulations and analytical modeling are employed. The initiation of an experimental effort to study force fields is described.

Unexpected Structures for Intercalation of Sodium in Epitaxial Graphene-SiC Interfaces (open access)

Unexpected Structures for Intercalation of Sodium in Epitaxial Graphene-SiC Interfaces

In this paper, the authors show using scanning tunneling microscopy, spectroscopy, and ab initio calculations that several intercalation structures exist for Na in epitaxial graphene on SiC(0001). Intercalation takes place at room temperature and Na electron-dopes the graphene. It intercalates in-between single-layer graphene and the carbon-rich interfacial layer. It also penetrates beneath the interfacial layer and decouples it to form a second graphene layer. This decoupling is accelerated by annealing and is verified by direct Na deposition onto the interface layer. The authors' observations show that intercalation in graphene is fundamentally different than in graphite and is a versatile means of electronic control.

Variability-Selected Low-Luminosity Active Galactic Nuclei in the 4 Ms Chandra Deep Field-South (open access)

Variability-Selected Low-Luminosity Active Galactic Nuclei in the 4 Ms Chandra Deep Field-South

This article demonstrates that the observed variability cannot be explained by X-ray Binary populations or ultraluminous X-ray sources, so the variability is most likely caused by accretion onto a supermassive black hole.
