What to do about system?

[fdmalone]

This is just a tuple of the electron numbers so seems pretty redundant? It's also sort of annoying to do import Generic as HamGeneric.

We should probably just delete and pass the tuple in as needed? The wavefunction will also store the number of electrons (and presumably the walker)

We kept it this way because we thought system could include information about symmetry too.
If we do k-points and space group symmetry, for instance, shouldn't that information be available through system?

[fdmalone]

What information are you thinking about? I would think the Hamiltonian would just have this information?

[linusjoonho]

Oh - is the list of k-points, for instance, a part of Hamiltonian?
Also, how about temperature?

[fdmalone]

I sort of feel like maybe these are just single parameters (temperature would be eaten by propagator for instance) and k-points which are a property of the Hamiltonian (they're in the definition of it, so it doesn't seem wrong right?) Anyway, not super important just popped into my head again.

I like the idea of removing the class, but somebody must make the changes everywhere, right?

[fdmalone]

yeah, maybe next time I get motivated I will do it. It's not urgent and fairly easy to do. Just using github issues to think out loud lol.
