This page gives hints on how to perform GWR calculations
|
|
|
|
## Introduction
|
|
|
|
A cubic scaling real-space imaginary-time algorithm for GW and RPA is available.
|
|
See the theory in [[cite:Liu2016]] and related references.
|
|
An overview is available in the tutorial [[tutorial:gwr_intro|An overview of the GWR code]].
|
|
|
|
This implementation relies on the minimax time-frequency grids
|
|
available in the GreenX library [[cite:Azizi2023]].
|
|
At present, only norm-conserving pseudopotentials can be used. The implementation is restricted to non-magnetic materials,
|
|
and without spin-orbit coupling.
|
|
Still, different types of flows and algorithms (including self-consistency) are available, see [[gwr_task]].
|
|
|
|
Activate it using [[optdriver]]=6, and specify [[gwr_task]].
|
|
|
|
NOTE: GWR code is under active development and not yet ready for production runs.
