One of our main activities is the development of the massively parallel QMC code QMC=Chem.

Current Features

Methods

  • VMC
  • DMC
  • Jastrow factor optimization

Wave functions

  • Single determinant
  • Multi-determinant
  • Multi-Jastrow
  • Nuclear cusp correction

Properties

Practical aspects

  • Very low memory requirements
  • Runs on a large number of processors
  • Checkpointing
  • Easy development with the IRPF90 tool.

Features under development

Methods

  • Wave function optimization

Properties

  • Molecular Forces
  • Moments (dipole, quadrupole,...)
  • Electron density
  • ZV-ZB EPLF estimator

Practical aspects

  • Graphical interface for input and output
