jaxrts.models.RPA

class jaxrts.models.RPA(sample_points: int | None = None)[source]

Model for free-free scattering based on the Random Phase Approximation. Solves the RPA integrals numerically.

Calculates the dielectric function in RPA and obtain a Structure factor via the fluctuation dissipation theorem. Implementation is based on lecture notes from M. Bonitz.

Requires a ‘chemical potential’ model (defaults to IchimaruChemPotential).

Methods

`__init__`([sample_points])
`check`(plasma_state)	Test if the model is applicable to the PlasmaState.

`evaluate`(plasma_state, setup, args, *kwargs)	If `sample_points` is not `None`, generate a low-resulution :py:class`~.setup.Setup`.
`evaluate_raw`(plasma_state, setup, *args, ...)
`prepare`(plasma_state, key)	Modify the plasma_state in place.
`sample_grid`(setup)	Define the sample-grid if `sample_points` is not `None`.
`susceptibility`(plasma_state, setup, E, ...)

Attributes
