Quantum-ESPRESSO (opEn-Source Package for Research in Electronic Structure, Simulation, and Optimization) is an integrated suite of computer codes, electronic-structure calculations and materials modeling at the nanoscale. It is based on density-functional theory, plane waves, and pseudopotentials (both norm-conserving and ultrasoft). The package includes PWscf and CP Plane-Wave basis set and pseudopotentials plus a Graphical User Interface for PWscf, a program for atomic calculations and generation of pseudopotentials, and an Input-Output Toolkit. Quantum-ESPRESSO runs on Unix machines. It is freely available to researchers around the world under the terms of the GNU General Public License.
