jaxrts.plasma_physics.noninteracting_susceptibility_from_eps_RPA(epsilon: Quantity, k: Quantity) → Quantity

Calculates the non-interacting susceptilibily from a given dielectric function epsilon in RPA.

See, e.g., [Fortmann et al., 2010].

..math:

\xi^{(0)}_{e} = \frac{1 - \varepsilon^{RPA}}{V_{ee}(k)}

Where \(V_{ee}\) is the Coulomb potential in k space.
