Detailed Description

Functor to evolve the optical depth of photons due to the Breit-Wheeler process

Constructor & Destructor Documentation

◆ BreitWheelerEvolveOpticalDepth() [1/2]

BreitWheelerEvolveOpticalDepth::BreitWheelerEvolveOpticalDepth ( )

inline

Default constructor: it leaves the functor in a non-initialized state.

◆ BreitWheelerEvolveOpticalDepth() [2/2]

BreitWheelerEvolveOpticalDepth::BreitWheelerEvolveOpticalDepth	(	const BW_dndt_table_view	table_view,
		const amrex::ParticleReal	bw_minimum_chi_phot
	)

inline

Constructor to be used to initialize the functor.

Parameters

[in]	table_view	a view of a BW_dndt_table lookup table
[in]	bw_minimum_chi_phot	the minimum quantum parameter to evolve the optical depth

inlinenoexcept

Evolves the optical depth. It can be used on GPU. If the quantum parameter parameter of the photon is < bw_minimum_chi_phot, the method returns immediately. The method returns also if the energy of the photon is insufficient to generate a pair.

Parameters

[in]	ux,uy,uz	gamma*v components of the photon.
[in]	ex,ey,ez	electric field components (SI units)
[in]	bx,by,bz	magnetic field components (SI units)
[in]	dt	timestep (SI units)
[in,out]	opt_depth	optical depth of the photon.

Returns: a flag which is 1 if chi_phot was out of table
