What is Quantum ESPRESSO?

Quantum ESPRESSO is an integrated suite of Open-Source computer codes for electronic-structure calculations and materials modeling at the nanoscale. It is based on density-functional theory, plane waves, and pseudopotentials.

Quantum ESPRESSO can be used for

  • Ground-state calculations
  • Structural Optimization
  • Transition states and minimum energy paths
  • Ab-initio molecular dynamics
  • Response properties (DFPT)
  • Spectroscopic properties
  • Quantum Transport

Using Quantum ESPRESSO

To use Quantum ESPRESSO, please use the following commands:

System QE Version Command
HPC2015 6.1 module load quantumespresso/impi/6.1
6.3 module load quantumespresso/impi/6.3
HPC2021 6.7 module load quantumespresso/6.7
