Abstract

This tool enables nanoHUB users to run quantum ESPRESSO, a powerful electronic structure code.

Users can perform total energy calculations, energy minimization to predict structures, obtain the Kohn-Sham band structure of periodic systems as well as phonons.

Version 2 includes: – Energy evolution plots – SCF output – Cell and force relax – Output of Stress and forces – Simultaneous bandstructure and phonon calculations

Quantum ESPRESSO: http://www.pwscf.org/ ""Quantum ESPRESSO is an integrated suite of computer codes for electronic-structure calculations and materials modeling at the nanoscale. It is based on density-functional theory, plane waves, and pseudopotentials (both norm-conserving, ultrasoft, and PAW)."
