@ -20,18 +20,19 @@ KCW stands for "Koopmans-compliant functionals in a Wannier representation". KCW
code which calculates quasiparticle energies of finite and extended systems using
[Koopmans-compliant functionals](https://journals.aps.org/prx/abstract/10.1103/PhysRevX.8.021051)
and [Maximally Localized Wannier Functions](http://journals.aps.org/prb/abstract/10.1103/PhysRevB.56.12847).
The code consists of 3 programs:
The details of this implementation are described [here](https://arxiv.org/abs/2202.08155).
The code consists of 3 modules specified by the "calculation" variable in CONTROL namelist:
1) an interface between Wannier90 and the KCW code (wann_to_kc.x)
1) interface between Wannier90 and the KCW code (calculation="wann_to_kc")
2) a program that computes the screening coefficients as described [here](https://pubs.acs.org/doi/abs/10.1021/acs.jctc.7b01116) (kc_screen.x)
2) calcuation of the screening coefficients (calculation="screen")
3) a program that computes the KC hamiltonian, interpolates it if needed, and finally diagonalizes it (kc_ham.x)
3) calculation, interpolation and diagonalization of the KC hamiltonian (calculation = "kc_ham")
KCW is developed and maintained by [Nicola Colonna](https://www.psi.ch/en/lns/people/nicola-colonna), [Riccardo de Gennaro](https://people.epfl.ch/riccardo.degennaro), and [Edward Linscott](https://people.epfl.ch/edward.linscott)

2) Initialize the xc-kernel and KC response as the spin-polarized one
also when nspin=1. This is needed to correctly define the perturbing
potentials. At the moment we do a nspin=2 calculation from the beginning
(not a big deal since the bottleneck is the LR calculation).
(not a big deal since the bottleneck is the LR calculation for which in
any case a spin-polarized response is needed).
