class jaxrts.models.StewartPyattPrestonIPD(arb_deg: bool = False, crowley_correction: bool = False)

Stewart Pyatt IPD Model [Stewart and Pyatt, 1966]. The Stewart–Pyatt model interpolates between the Debye–Hückel [Debye and Hückel, 1923] and Ion-Sphere model [Rozsnyai, 1972] at (low temperature, high density) and (high temperature, low density), respectively.

Uses the formulation that can be found in [Preston et al., 2013], which is close to the original work of [Stewart and Pyatt, 1966], but is formulated in a way that requires knowledge over the distribution of all plasma states. See Appendix A of [Pain, 2022] for how to obtain the Model implemented in :py:class:~.StewartPyattIPD` from this Model.

Allows for the arb_deg flag, which solves Fermi integrals to obtain the Debye screening length, rather than using the classical formula.

A correction presented in [Crowley, 2014] can be switched on with the crowley_correction flag.
