QUANTUM ESPRESSO: a modular and open-source software project for quantum simulations of materials

TL;DR: QUANTUM ESPRESSO as discussed by the authors is an integrated suite of computer codes for electronic-structure calculations and materials modeling, based on density functional theory, plane waves, and pseudopotentials (norm-conserving, ultrasoft, and projector-augmented wave).
Journal ArticleDOI

Unified Approach for Molecular Dynamics and Density-Functional Theory

TL;DR: In this article, a unified scheme combining molecular dynamics and density-functional theory is presented, which makes possible the simulation of both covalently bonded and metallic systems and permits the application of density functional theory to much larger systems than previously feasible.
Journal ArticleDOI

Raman Spectra of Graphite Oxide and Functionalized Graphene Sheets

TL;DR: Only the alternating pattern of single-double carbon bonds within the sp2 carbon ribbons provides a satisfactory explanation for the experimentally observed blue shift of the G band of the Raman spectra relative to graphite.
Journal ArticleDOI

Advanced capabilities for materials modelling with Quantum ESPRESSO.

Paolo Giannozzi, +53 more
TL;DR: Recent extensions and improvements are described, covering new methodologies and property calculators, improved parallelization, code modularization, and extended interoperability both within the distribution and with external software.
