Abstract

The advent in this century of nano and microelectronics requires, by part of physicists and engineers, the need of an explanation of electrical phenomena such as the interaction of a body with external electric fields at its atomic level,i.e. where is the case of the appearance of the quantum nature of phenomena involved in the projecting of nano an micro devices. It is mainly focused in this article the problem of calculating eigenstates of quantum matter interacting with a uniform external electric field, whose solution is reported via a DFT(Density Functional Theory) variational approach[3,4].
