use Photonic::OneH::R2; my $nr=Photonic::OneH::R2->new(metric=>$g, polarization=>$p); $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 retarded dielectric function of arbitrary periodic two component systems in arbitrary number of dimentions. One Haydock coefficient at a time.
new(metric=>$m, polarization=>$e, [, smallH=>$s])
Create a new Ph::OneH::R2 object with PDL::Metric::R2 $m, with a field along the complex direction $e and with smallness parameter $s.
A Photonic::Metric::R2 object defining the geometry of the system, the charateristic function, the wavenumber, wavevector and host dielectric function. Required in the initializer.
A non null vector defining the complex direction of the macroscopic field.
A small number used as tolerance to end the iteration. Small negative b^2 coefficients are taken to be zero.
B ndims dims epsilon
Accesors handled by metric (see Photonic::Metric::R2)
previousState currentState nextState
The n-1-th, n-th and n+1-th Haydock states; a complex vector for each reciprocal wavevector
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
The n+1-th c Haydock coefficient
previous_g current_g next_g
The n-1-th n-th and n+1-th g Haydock coefficients
Number of completed iterations
Performs a single Haydock iteration and updates current_a, next_b, next_b2, next_c, next_g, next_state, shifting the current values where necessary. Returns 0 when unable to continue iterating.
Returns the result of applying the metric 'g' to the state; $psi.
Apply the Hamiltonian operator to state. The Hamiltonian is Bg, with g the metric and B the characteriztic function. Also applies an optional mask in reciprocal space.
Returns the inner Hermitian product between states using the metric.
Returns the magnitude of a state as the square root of the inner product of the state with itself.
Returns 1 if sign change is required to ensure b^2 is positive.
Returns the fisrt state $v.
