Detailed Description

IDR_DRMD: Dark Radiation in the DRMD model.

Member Function Documentation

◆ GetOmega0()

double IDR_DRMDSpecies::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.

◆ GetRadiationOmega0()

double IDR_DRMDSpecies::GetRadiationOmega0 ( ) const

inlineoverridevirtual

IDR_DRMD is dark radiation: contributes its Omega0 to the early-time radiation density.

Reimplemented from BaseSpecies.

◆ IsFreestreaming()

bool IDR_DRMDSpecies::IsFreestreaming ( ) const

inlineoverridevirtual

True for species that are free-streaming and massless at IC time (deep radiation domination). Used to accumulate rho_nu / fracnu in perturbation IC setup. Static at construction time. Default: false.

Reimplemented from BaseSpecies.

◆ RegisterBackgroundIndices()

void IDR_DRMDSpecies::RegisterBackgroundIndices ( int & index_bg )

inlineoverridevirtual

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.

◆ ComputeBackground()

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

inlineoverridevirtual

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 IDR_DRMDSpecies::Rho ( const double * pvecback ) const

inlineoverridevirtual

Energy density at current background state.

Implements BaseSpecies.

◆ P()

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

inlineoverridevirtual

Pressure at current background state.

Implements BaseSpecies.

◆ PPrime()

double IDR_DRMDSpecies::PPrime	(	double	a,
		double	H,
		const double *	pvecback_B,
		const double *	pvecback
	)		const

inlineoverridevirtual

Post-Friedmann. This species' conformal-time pressure derivative p' (a' / a = a*H). pvecback_B is the ODE state (IN); pvecback is fully populated through H. Default 0 (matter / Lambda).

Reimplemented from BaseSpecies.

◆ CreatePerturbLayout()

std::unique_ptr< BaseSpecies::PerturbLayout > IDR_DRMDSpecies::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.

◆ PerturbDerivs()

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

overridevirtual

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.

◆ StressEnergy()

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

overridevirtual

All scalar stress-energy perturbations in one call.

Implements BaseSpecies.

◆ PerturbSynchronousToNewtonian()

void IDR_DRMDSpecies::PerturbSynchronousToNewtonian	(	const BaseSpecies::PerturbLayout &	,
		double *	,
		const PerturbIcContext &
	)

overridevirtual

Transform this species' own perturbation variables from synchronous to Newtonian gauge, in place in y[]. Called by the module after alpha is known (ctx.alpha / ctx.alpha_prime filled). The synchronous IC is already in y[] (ApplyInitialConditions runs in both gauges), so this is a pure shift/re-seed. Default: no-op (species with no perturbed variables, e.g. cosmological constant).

Reimplemented from BaseSpecies.

◆ CopyPerturbationsAcrossSwitch()

void IDR_DRMDSpecies::CopyPerturbationsAcrossSwitch	(	const BaseSpecies::PerturbLayout &	,
		const BaseSpecies::PerturbLayout &	,
		const double *	,
		double *	,
		const PerturbSwitchContext &
	)		const

overridevirtual

Copy perturbation state from one layout to another across an approximation switch. Called when the perturbation vector is reallocated (e.g., NCDM FA collapse from full Boltzmann hierarchy to fluid variables delta/theta/shear). Default: no-op. Most species have no approximation switches.

Reimplemented from BaseSpecies.
