use Photonic::LE::NP::OneH; my $nr=Photonic::LE::NP::OneH->new(epsilon=>$epsilon, geometry=>$geometry); $nr->iterate; say $nr->iteration; say $nr->current_a; say $nr->next_b2; my $state=$nr->nextState;
Implements calculation of Haydock coefficients and Haydock states for the calculation of the non retarded dielectric function of arbitrary periodic many component systems in arbitrary number of dimentions. One Haydock coefficient at a time. The starting state is homogenous.
new(epsilon=>$e, geometry=>$g[, smallH=>$s])
Create a new Ph::NR::NP::OneH object with GeometryG0 $g, dielectric function $e and optional smallness parameter $s.
A PDL::Complex PDL giving the value of the dielectric function epsilon for each pixel of the system
A Photonic::Geometry object defining the geometry of the system, the charateristic function and the direction of the G=0 vector. Should be given in the initializer.
B ndims dims r G GNorm L scale f
Accesors handled by geometry (see Photonic::Geometry)
A small number used as tolerance to end the iteration. Small negative b^2 coefficients are taken to be zero.
previousState currentState nextState
The n-1-th, n-th and n+1-th Haydock states; a complex number for each pixel
The n-th Haydock coefficient a
current_b2 next_b2 current_b next_b
The n-th and n+1-th b^2 and b Haydock coefficients
Number of completed iterations
Performs a single Haydock iteration and updates current_a, next_state, next_b2, next_b, shifting the current values where necessary. Returns 0 when unable to continue iterating.
Apply the 'Hamiltonian' operator to state $psi_G in reciprocal =space. State is ri:nx:ny... The operator is the longitudinal projection of the dielectric function
Returns the inner (Euclidean) product between states $left and $right.
Returns the magnitude of state $psi_G in reciprocal space by taking the square root of the inner product of the state with itself.
Returns zero, as there is no need to change sign.
Returns the fisrt state.
