positron

This page gives hints on how to set parameters for a calculation with a positron in the system with the ABINIT package.

Introduction

The lifetime of a positron, its annihilation rate and other associated properties can be computed, using the self-consistent two-component DFT formalism, including force and stress computation (and thus relaxation), LDA and GGA, wirhin norm-conserving pseudopotentials as well as PAW approach [Wiktor2015].

Doppler broadening can also be computed. The details of the way to perform such calculations are given in the description of the positron input variable, as well as in the tutorial on electron-positron annihilation.

Examples can be found in [Wiktor2013], [Wiktor2014], [Wiktor2014a] and [Wiktor2014b].
