Theory of Edge States in Systems with Rashba Spin-Orbit Coupling
A. Reynoso, Gonzalo Usaj, M. J. Sanchez +1
We study the edge states in a two dimensional electron gas with a transverse magnetic field and Rashba spin-orbit coupling. In the bulk, the interplay between the external field pe…
The effect of biodiversity on the Hantavirus epizootic
Ignacio D. Peixoto, Guillermo Abramson
We analyze a mathematical model of the epizootic of Hantavirus in mice population, including the effect of species which compete with the host. We show that the existence of the se…
Anisotropy in Ferromagnetic Nanoparticles: Level-to-Level Fluctuations of a Collective Effect
Gonzalo Usaj, Harold U. Baranger
We calculate the mesoscopic fluctuations of the magnetic anisotropy of ferromagnetic nanoparticles. A microscopic spin-orbit Hamiltonian considered as a perturbation of the much st…
Tuning the Non-local Spin-Spin Interaction between Quantum Dots with a Magnetic Field
Gonzalo Usaj, P. Lustemberg, C. A. Balseiro
We describe a device where the non-local spin-spin interaction between two quantum dots can be turned on and off and even changed sign with a very small magnetic field. The setup c…
Zipf's law and the creation of musical context
Damian H. Zanette
This article discusses the extension of the notion of context from linguistics to the domain of music. In language, the statistical regularity known as Zipf's law -which concerns t…
Transverse Electron Focusing in Systems with Spin-Orbit Coupling
Gonzalo Usaj, C. A. Balseiro
We study the transverse electron focusing in a two dimensional electron gas with Rashba spin-orbit coupling. We show that the interplay between the external magnetic field and the…
