Vortex motion rectification in Josephson junction arrays with a ratchet potential
D. E. Shalom, H. Pastoriza
By means of electrical transport measurements we have studied the rectified motion of vortices in ratchet potentials engineered on over-damped Josephson junction arrays. The rectif…
Magnetic Moment Formation in Quantum Point Contacts
P. S. Cornaglia, C. A. Balseiro, M. Avignon
We study the formation of local magnetic moments in quantum point contacts. Using a Hubbard-like model to describe point contacts formed in a two dimensional system, we calculate t…
Heterogeneous dynamics of the three dimensional Coulomb glass out of equilibrium
Alejandro B. Kolton, D. R. Grempel, Daniel Dominguez
The non-equilibrium relaxational properties of a three dimensional Coulomb glass model are investigated by kinetic Monte Carlo simulations. Our results suggest a transition from st…
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…
