Critical phenomena in the spreading of opinion consensus and disagreement
Andrés Chacoma, Damián H. Zanette
We consider a class of models of opinion formation where the dissemination of individual opinions occurs through the spreading of local consensus and disagreement. We study the eme…
Avoiding extinction by migration: The case of the head louse
Octavio Cabrera, Damián H. Zanette
The possibility of spreading by migration, colonizing new spatial domains suitable for development and reproduction, can substantially relieve a biological population from the risk…
Critical behavior and out-of-equilibrium dynamics of a two-dimensional Ising model with dynamic couplings
Oscar A. Pinto, Federico Romá, Sebastian Bustingorry
We study the critical behavior and the out-of-equilibrium dynamics of a two-dimensional Ising model with non-static interactions. In our model, bonds are dynamically changing accor…
Duffing revisited: Phase-shift control and internal resonance in self-sustained oscillators
Sebastián I. Arroyo, Damián H. Zanette
We address two aspects of the dynamics of the forced Duffing oscillator which are relevant to the technology of micromechanical devices and, at the same time, have intrinsic signif…
Multiband character of -FeSe: Angular dependence of the magnetoresistance and upper critical field
M. L. Amigó, V. Ale Crivillero, D. G. Franco +1
We studied -plane transport properties in single crystals of the superconductor -FeSe up to 16 T. In the normal state, below 90 K, the crystals present a strongly anisotropi…
Temperature evolution of the effective magnetic anisotropy in the MnCrO spinel
Dina Tobia, Julián Milano, María Teresa Causa +1
In this work we present a study of the low temperature magnetic phases of polycrystalline MnCrO spinel through dc magnetization and ferromagnetic resonance spectroscopy (FM…
