apply()

void q3::NoPreconditioner::apply ( std::vector< Complex > &  residual_g ) const

inlineoverridevirtual

Apply the preconditioner to one G-space residual channel, in place.

Callers pass the TOTAL charge channel only: the magnetization channel has no Coulomb kernel to screen, and damping its long-wavelength components would freeze slow moment relaxation. The G = 0 component must be left untouched — it is fixed by charge conservation, and the mixing metric excludes it for the same reason.

Parameters

residual_g

residual in reciprocal space; overwritten with the preconditioned residual.
