O modelo de tight-binding é um dos pilares da Física da Matéria Condensada, permitindo descrever de forma bastante simples uma ampla gama de fenômenos de interesse, como por exemplo a estrutura de bandas dos materiais e o transporte eletrônico.

A dinâmica do spin é um dos problemas mais importantes da Física Moderna e seu estudo rendeu o prêmio Nobel de Física a vários cientistas importantes do século XX, cabendo destacar os nomes de Rabi, Bloch e Purcell. No entanto, dada a complexi

O grafeno é um material alotrópicoo do carbono, formado por uma monocamada de átomos de carbono arranjados em uma estrutura cristalina de favo de mel (ou honeycomb), podendo ser obtido por diversos métodos experimentais, sendo a esfoliação do g

Electrons near the Fermi level behaving as massless Dirac fermions in graphene in (1+2)-D relativistic spacetime have been confirmed by an experiment. Using this aspect, a myriad of novel and interesting devices can be sought. In this paper, we laid

We propose a model of electroweak interactions without chirality in a six-dimensional spacetime with 3 time-like and 3 space-like coordinates, which allows a geometrical meaning for gauge symmetries. The spacetime interval ds 2=dx μ dx μ is left in

In this paper we analyze different contributions to the magnetoresistance of magnetic tunneling junctions at low voltages. A substantial fraction of the resistance drop with voltage can be ascribed to variations of the density of states and the barri

In this paper we analyze the main transport properties of a simple resonant magnetic tunnel junction (FM-IS-METAL-IS-FM structure) taking into account both elastic and magnon-assisted tunneling processes at low voltages and temperatures near 0°K. We
