Single-particle model for a granular ratchet

A. J. Bae, W. A. M. Morgado, J. J. P. Veerman +1

A simple model for a granular ratchet corresponding to a single grain bouncing off a vertically vibrating sawtooth-like base is studied. Depending on the vibration strength, the sa…

Some Remarks on the Geodesic Completeness of Compact Nonpositively Curved Spaces

Pedro Ontaneda

We make some remarks on the existence of a geodesically complete core for any compact non-positively curved space.

On the Field Dependence of the Interface Energy in Af/FM Bilayers

J. R. L. de Almeida, J. R. Steiner, S. M. Rezende

In the investigations of antiferromagnetic (AF)/ ferromagnetic (FM) bilayer samples, often distinct experimental techniques yield different values for the measured exchange anisotr…

Quantifying a certain advantage law: minority game with above the rules agents

J. R. L. de Almeida, J. Menche

In this work the properties of minority games containing agents which try to winning all the time are studied by means of computational simulations. We have considered several ways…

Stochastic description of the dynamics of the random-exchange Heisenberg chain

M. H. Vainstein, R. Morgado, F. A. Oliveira +2

We study the diffusion process in a Heisenberg chain with correlated spatial disorder, with a power spectrum in the momentum space behaving as , using a stochastic descript…
