Role of Interstitial Pinning in the Dynamical Phases of Vortices in Superconducting Films
R. P. Simões, P. A. Venegas, D. F. Mello
We analyze the vortex dynamics in superconducting thin films with a periodic array of pinning centers. In particular, we study the effect of anisotropy for a Kagomé pinning network…

The Effects of Pinning on Critical Currents of Superconducting Films
R. P. Simões, P. A. Venegas, D. F. Mello
Using molecular dynamics simulations, we analyze the effects of artificial periodic arrays of pinning sites on the critical current of superconducting thin films as a function of v…

Local order and magnetic field effects on the electronic properties of disordered binary alloys in the Quantum Site Percolation limit
D. F. de Mello, G. G. Cabrera
Electronic properties of disordered binary alloys are studied via the calculation of the average Density of States (DOS) in two and three dimensions. We propose a new approximate s…
