Using numerical simulations, we analyze the anisotropy effects in the critical currents and dynamical properties of vortices in a thin superconducting film submitted to hexagonal and Kagomé periodical pinning arrays. The ...

The numerical renormalization group is an efficient method to diagonalize model Hamiltonians describing correlated orbitals coupled to conduction states. While only the resulting eigenvalues are needed to calculate the ...

Many studies have discussed the effects of coarse aggregate on the mechanical properties of concrete, but this is not the case of the transport properties. The evaluation of the behaviour of old concretes becomes of interest ...

Some dynamical properties for an ensemble of non-interacting classical particles along chaotic orbits and transport properties over the chaotic sea for the problem of a step and time dependent potential well are considered. ...

Thin films of tin dioxide (SnO2) are deposited by the sol-gel-dip-coating technique, along with GaAs layers, deposited by the resistive evaporation technique. The as-built heterojunction has potential application in ...

Some statistical properties related to the diffusion in energy for an ensemble of classical particles in a bouncing ball model are studied. The particles are confined to bounce between two rigid walls. One of them is fixed ...

Abstract: Silica matrices are suitable for encapsulation of biomolecules and microorganisms to build bioactive functional materials. For many applications of these host–guest systems, the performance highly depends on the ...

The electronic structure and transport properties of a single layer of graphene (Gr) on α-Al2O3 surface are studied using the density functional theory (DFT). We present three models that take into account the atom at the ...
