First-principles calculation method for electron transport based on the grid Lippmann-Schwinger equation.
We develop a first-principles electron-transport simulator based on the Lippmann-Schwinger (LS) equation within the framework of the real-space finite-difference scheme. In our fully real-space-based LS (grid LS) method, the ratio expression technique for the scattering wave functions and the Green's function elements of the reference system is employed to avoid numerical collapse. Furthermore,...
متن کاملFirst-Principles Calculation of Transport Coefficients
We demonstrate the practical feasibility of calculating transport coefficients such as the viscosity of liquids completely from first principles using the Green-Kubo relations. Results presented for liquid aluminum are shown to have a statistical error of only ca. 5%. The importance of such calculations is illustrated by results for a liquid iron-sulfur alloy under Earth’s core conditions, whic...

متن کاملThe new implicit finite difference scheme for two-sided space-time fractional partial differential equation
Fractional order partial differential equations are generalizations of classical partial differential equations. Increasingly, these models are used in applications such as fluid flow, finance and others. In this paper we examine some practical numerical methods to solve a class of initial- boundary value fractional partial differential equations with variable coefficients on a finite domain. S...
متن کاملFirst-principles Calculation of Transport Properties of Nanostructures
(1) Na wire [2] The single-row sodium nanowires exhibit conductance oscillation and bunching of high electron density with two atom-lengths in the channel density distribution. The relationship between the period of the conductance oscillation and the length of the bunches is interpreted using a simplified model. The difference in the penetration parameters between the incident Bloch wave and t...
