[sympy] Matt Curry's GSoC Proposal Draft

[Matt Curry]

Hello everyone,

I'm currently a Physics major at Cal Poly. I'm interested in adding
quantum mechanics to SymPy through Google Summer of Code. I've
included the link to my current proposal draft. Any input would be
helpful!

Thanks,

Matt Curry

Hi.

I am assuming you are one of Brian Granger's students that he mentioned here.

I think the proposal looks good. I don't know anything about Quantum Mechanics, so I can't say anything about the actual content. Hopefully Ondrej, Brian, Øyvind, etc. will be able to help you with that.

One thing I would add is how it would be beneficial to have this written in Python. It's suggested to submit to both the Python Software Foundation and Portland State University. Of course, PSF will already know how awesome Python is, but the guys at PSU might not.

Also, you might want to mention what has already been implemented in SymPy (for example, you mention second quantization, but I believe we already have some second quantization implemented).

So what are the closed source approaches? Is there anything out there that can act as a guide?

By the way, go ahead and submit the proposal to PSF and PSU. You can edit it up until the deadline tomorrow.

Thank's for the input! Other input still appreciated!

I think your proposal looks very solid. We have last 3 hours to the
deadline, so I only have this suggestion:

Put there some example section, where you would show on examples, how
your module will be used. I.e.

Examples

>>> a = TensorProduct(..., ...)
>>> a
<a|x|x>
>>> b = <define harmonic oscillator>
>>> b.solve()
[gives levels of h1d]

^^^ this is just for inspiration, simply put there what you want to
implement and show it on examples, so that people (reviewers) can
quickly get an idea what functionality will be implemented and how it
will be used.

Apart from that, it looks cool!

I just updated the link with my final proposal. Thanks for all your
help!

I think this is related to the geometric algebra module in sympy, it
also defines some inner and outer products, if I recall it correctly.

In "Gemetric Algebra for Physicist" by Doran and Lasenby in chapters 8
and 9 they derive the correspondence between quantum mechanical state
vectors and the multivectors of geometric (clifford) algebra for both
single particle and multiparticle states. The reason this is useful is
because spinors (both 3d and 4d) are trivial in geometric algebra.
