Application of Entropy and Fractal Dimension Analyses to the Pattern Recognition of Contaminated Fish Responses in Aquaculture
(MDPI, 2014-11)
The objective of the work was to develop a non-invasive methodology for image acquisition, processing and nonlinear trajectory analysis of the collective fish response to a stochastic event. Object detection and motion ...
Defect and structural imperfection effects on the electronic properties of BiTeI surfaces
(IOP Publishing, 2014-07-24)
The surface electronic structure of the narrow-gap seminconductor BiTeI exhibits a large Rashba-splitting which strongly depends on the surface termination. Here we report on a detailed investigation of the surface morphology ...
Electronic properties of graphene grain boundaries
(IOP Publishing, 2014-08-08)
Grain boundaries and defect lines in graphene are intensively studied for their novel electronic and magnetic properties. However, there is not a complete comprehension of the appearance of localized states along these ...
Acoustic plasmons in extrinsic free-standing graphene
(IOP Publishing, 2014-08-04)
An acoustic plasmon is predicted to occur, in addition to the conventional two-dimensional (2D) plasmon, as the collective motion of a system of two types of electronic carriers coexisting in the same 2D band of extrinsic ...
Germanene: a novel two-dimensional germanium allotrope akin to graphene and silicene
(IOP Publishing, 2014-09-09)
We have grown an atom-thin, ordered, two-dimensional multi-phase film in situ through germanium molecular beam epitaxy using a gold (111) surface as a substrate. Its growth is similar to the formation of silicene layers ...
Giant diamagnetism of gold nanorods
(IOP Publishing, 2014-07-30)
The presence of giant diamagnetism in Au nanorods, NRs, is shown to be a possible consequence of field induced currents in the surface electrons. The distance, Delta , between quantum surface energy levels has been calculated ...
Dual-path methods for propagating quantum microwaves
(IOP Publishing, 2014-01)
We study quantum state tomography, entanglement detection and channel noise reconstruction of propagating quantum microwaves via dual-path methods. The presented schemes make use of the following key elements: propagation ...
A chemically inert Rashba split interface electronic structure of C-60, FeOEP and PTCDA on BiAg2/Ag(111) substrates
(IOP Publishing, 2014-04-04)
The fields of organic electronics and spintronics have the potential to revolutionize the electronics industry. Finding the right materials that can retain their electrical and spin properties when combined is a technological ...
Entanglement negativity in the harmonic chain out of equilibrium
(IOP Publishing, 2014-12-08)
We study the entanglement in a chain of harmonic oscillators driven out of equilibrium by preparing the two sides of the system at different temperatures, and subsequently joining them together. The steady state is constructed ...
Metallic thin fi lms on stepped surfaces: lateral scattering of quantum well states
(IOP Publishing, 2014-12-10)
Quantum well states of Ag films grown on stepped Au(111) surfaces are shown to undergo lateral scattering, in analogy with surface states of vicinal Ag(111). Applying angle resolved photoemission spectroscopy we observe ...
