add the Potekhin and Chabrier (2010,2013) EOS

[zingale]

The Potekhin and Chabrier (2010,2013) EOS is freely available (in Fortran) here:

http://www.ioffe.ru/astro/EIP/

This EOS seems to be preferred by MESA:

https://docs.mesastar.org/en/r15140/eos/overview.html

There is also support here for a magnetized plasma.

Note: there is no license available here.

in particular, MESA says:

The PC EOS (Potekhin & Chabrier 2010) is a fully-ionized electron-ion plasma EOS. It includes a detailed treatment of Coulomb interactions and so is prefered once the Coulomb coupling paramter becomes significant. It includes the phase transition associated with ion crystallization. The composition is accounted for by including all isotopes with mass fractions above a specified minimum.

I've exchanged email with the author and he is fine with us putting a C++ port in our code under a BSD license. Note: we will include language in the docs asking users to be sure to cite the EOS papers.

Dear Mike,

Yes, it will be fine with me, go ahead!

Best regards,

Thanks for getting back to me Sasha.  

We would like to use this with our code, which is BSD licensed.  What we would do is rewrite the EOS in C++ so we can use it on GPUs with our GPU offloading strategy (C++ lambda captures).  So I guess a more direct question is that if we did this, would you be okay with us including the C++ ported version in our repo under a BSD license with instructions to cite your EOS papers if it is used?

Mike
