On the importance of grain boundaries in high-Tc films: simulation results
R. Mulet, E. Altshuler
The importance of the distribution and ``weakness'' of grain boundary junctions in the magnetic field dependence of the transport critical current in HTc films is assessed through…

Models for Free Granular Surfaces
R. Mulet, H. Herrmann
We introduce two sets of continuum equations to describe granular flow on a free surface and study their properties. The equations derived from a microscopic picture that includes…
