jaxrts.hnc_potentials.SoftCorePotential

class jaxrts.hnc_potentials.SoftCorePotential(beta: float = 4.0)

Comparable to EmptyCorePotential, but to circumvent the hard cutoff, rather introduce a soft, exponential cutoff. It’s strength is given by the attribute beta. See [Gericke et al., 2010].

We define r_cut in the jaxrts.PlasmaState.

Warning

This potential is only defined for the electron-ion interaction. Hence, it will always and automatically set ~:py:meth:include_electrons to "SpinAveraged". For the rest, we return a Coulomb-potential – but this is really just to be compatible with the other potentials defined here.

Methods

T(plasma_state)	The mass_weighted temperature average of a pair, according to [Schwarz et al., 2007].
__init__([beta])
alpha(plasma_state)
check(plasma_state)	Test if the HNCPotential is applicable to the PlasmaState.
citation([style, comment])	Return bibliographic information for the Model used.
full_k(plasma_state, k)
full_r(plasma_state, r)
lambda_ab(plasma_state)
long_k(plasma_state, k)
long_r(plasma_state, r)
mu(plasma_state)	The geometric mean of two masses (or reciprocal sum)
prepare(plasma_state, key)
q2(plasma_state)	This is \(q^2\)!
r_cut(plasma_state)	This casts jaxrts.PlasmaState.ion_core_radius in the form required to be used with an :py:class:~.HNCPotential`.
short_k(plasma_state, k)
short_r(plasma_state, r)

Attributes

allowed_keys	A list of keys where this Potential is adequate for.
cite_keys	A list of bibtex keys.
beta	This is the exponent which gives the steepness of the soft-core's edge
include_electrons	If "SpinAveraged", the electrons are added as the n+1th ion species to the potential.
