RKKY interaction between extended magnetic defect lines in graphene
(2014)Of fundamental interest in the field of spintronics is the mechanism of indirect exchange coupling between magnetic impurities embedded in metallic hosts. A range of physical features, such as magnetotransport and overall ... -
Strain-modified RKKY interaction in carbon nanotubes
(2015)For low-dimensional metallic structures, such as nanotubes, the exchange coupling between localized magnetic dopants is predicted to decay slowly with separation. The long-range character of this interaction plays a ... -
There are many ways to spin a photon: Half-quantization of a total optical angular momentum
(2016)The angular momentum of light plays an important role in many areas, from optical trapping to quantum information. In the usual three-dimensional setting, the angular momentum quantum numbers of the photon are integers, ... -
X-ray spectroscopic studies of the electronic structure of chromium-based p-type transparent conducting oxides
(2016)The valence band structure of p-type transparent oxides—crystalline MgxCr2−xO3 and nanocrystalline CuxCrOy—is analyzed as a function of incoming photon energy. The valence band of both p-type transparent conducting oxides ... -
Z-Cone model for the energy of an ordered foam
(2014)We develop the Z-Cone Model, in terms of which the energy of a foam may be estimated. It is directly applicable to an ordered structure in which every bubble has Z identical neighbours. The energy (i.e. surface area) may ...
