Detailed Description

Cosmological constant (Lambda) species.

Background: rho_lambda = Omega0_lambda * H0^2 (constant), p_lambda = -rho_lambda (w = -1), dp/dloga = 0. Perturbations: none (Lambda is homogeneous).

Member Function Documentation

◆ GetOmega0()

double LambdaSpecies::GetOmega0 ( ) const

inlineoverridevirtual

Returns the species' contribution to Omega0 (used for budget closure during construction). For composites, this defaults to summing children. For decay-product species starting at zero, override returning 0.

Implements BaseSpecies.

◆ CreatePerturbLayout()

std::unique_ptr< BaseSpecies::PerturbLayout > LambdaSpecies::CreatePerturbLayout ( ) const

inlineoverridevirtual

Produce a fresh layout for this species. Called once per pv during perturb_vector_init, before Register*PerturbationIndices. Default: empty base PerturbLayout (suitable for species with no perturbation slots, or as a placeholder during migration).

Reimplemented from BaseSpecies.

◆ RegisterBackgroundIndices()

void LambdaSpecies::RegisterBackgroundIndices ( int & index_bg )

overridevirtual

Claim consecutive slots in pvecback. Called once during background_indices(). Implementation must assign index_bg_rho_ (and any other needed indices) and increment index_bg accordingly.

Implements BaseSpecies.

◆ WriteBackgroundColumnTitles()

void LambdaSpecies::WriteBackgroundColumnTitles ( BackgroundColumnWriter & ) const

overridevirtual

Write this species' background column titles into writer. Called by BackgroundModule::background_output_titles(). Default: no-op (species with no background output need not override).

Reimplemented from BaseSpecies.

◆ WriteBackgroundData()

void LambdaSpecies::WriteBackgroundData	(	const double *	,
		BackgroundColumnWriter &
	)		const

overridevirtual

Write this species' background data values into writer. pvecback is the full background vector at the current time step. Called by BackgroundModule::background_output_data(). Default: no-op.

Reimplemented from BaseSpecies.

◆ ComputeBackground()

void LambdaSpecies::ComputeBackground	(	double	a,
		const double *	pvecback_B,
		double *	pvecback
	)

overridevirtual

Compute species background quantities at scale factor a. pvecback_B is the current ODE integration vector. Write density (and any other owned quantities) into pvecback.

Implements BaseSpecies.

◆ Rho()

double LambdaSpecies::Rho ( const double * pvecback ) const

overridevirtual

Energy density at current background state.

Implements BaseSpecies.

◆ P()

double LambdaSpecies::P ( const double * pvecback ) const

overridevirtual

Pressure at current background state.

Implements BaseSpecies.

◆ StressEnergy()

StressEnergyContribution LambdaSpecies::StressEnergy	(	const BaseSpecies::PerturbLayout &	layout,
		const perturb_vector *	pv,
		const double *	y,
		const double *	pvecback,
		const perturb_workspace *	ppw
	)		const

inlineoverridevirtual

All scalar stress-energy perturbations in one call.

Implements BaseSpecies.

◆ PerturbDerivs()

void LambdaSpecies::PerturbDerivs	(	const BaseSpecies::PerturbLayout &	layout,
		double	tau,
		const double *	y,
		double *	dy,
		const perturb_parameters_and_workspace &	ppaw
	)		const

inlineoverridevirtual

Contribute to dy for the scalar perturbation ODE at conformal time tau. The PerturbScalarContext inside ppaw->ppw has pre-computed metric terms, cross-species state (delta_g, theta_g, theta_b, ...), and approximation flags. The layout is this species' PerturbLayout slot (ppw->pv->species_layouts[i]); composites receive their own layout and pass nested sub-layouts to children.

Implements BaseSpecies.
