Scalable implementation of polynomial filtering for density functional theory calculation in PARSEC

Density functional theory calculation of edge stresses in monolayer MoS2

development and implementation of an optimized control strategy for induction machine in an electric vehicle

in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...

Localized-density-matrix implementation of time-dependent density-functional theory

Polynomial filtered Lanczos iterations with applications in Density Functional Theory

The most expensive part of all Electronic Structure Calculations based on Density Functional Theory, lies in the computation of an invariant subspace associated with some of the smallest eigenvalues of a discretized Hamiltonian operator. The dimension of this subspace typically depends on the total number of valence electrons in the system, and can easily reach hundreds or even thousands when l...

Calculation of phononic and thermal properties of the CaB2 using the perturbation density functional theory (Research Article)

In this paper, the phononic structure and Enthalpy of CaB2 compound in simple hexagonal and orthorhombic phase have been investigated. The calculations were performed using the pseudo-potential method in the framework of the density functional theory and using the Quantum-Espresso code. Using the group theory and the characteristic table of the composition point group, the phonon modes were ide...
