phase_set_phase_corr()

subroutine phase_oct_m::phase_set_phase_corr ( class(phase_t), intent(in)  phase, class(mesh_t), intent(in)  mesh, type(wfs_elec_t), intent(inout)  psib, logical, intent(in), optional  async  )

private

set the phase correction (if necessary)

phase_unset_phase_corr()

subroutine phase_oct_m::phase_unset_phase_corr ( class(phase_t), intent(in)  phase, class(mesh_t), intent(in)  mesh, type(wfs_elec_t), intent(inout)  psib, logical, intent(in), optional  async  )

private

unset the phase correction (if necessary)

Definition at line 455 of file phase.F90.

phase_apply_batch()

subroutine phase_oct_m::phase_apply_batch ( class(phase_t), intent(in)  this, class(mesh_t), intent(in)  mesh, integer, intent(in)  np, logical, intent(in)  conjugate, type(wfs_elec_t), intent(inout), target  psib, type(wfs_elec_t), intent(in), optional, target  src, logical, intent(in), optional  async  )

apply (remove) the phase to the wave functions before (after) applying the Hamiltonian

Definition at line 480 of file phase.F90.

phase_apply_mf()

subroutine phase_oct_m::phase_apply_mf ( class(phase_t), intent(in)  this, complex(real64), dimension(:, :), intent(inout)  psi, integer, intent(in)  np, integer, intent(in)  dim, integer, intent(in)  ik, logical, intent(in)  conjugate  )

private

apply (or remove) the phase to a wave function psi

States are usually stored without the phase. Due to the phase convention (exp(-i phase())), the phase is applied by multiplying with the complex conjugate of the phase() function, and removed by multiplying with phase().

Parameters

[in,out]	psi	the complex wave function
[in]	np	number of points
[in]	conjugate	if .false.: apply the phase, if .true.: remove the phase

phase_is_allocated()

logical pure function phase_oct_m::phase_is_allocated ( class(phase_t), intent(in)  this )

private
