Hello /sci/. I am a physics and applied math double major, and I am in an independent research seminar where I need to do a research project. I decided to double major fairly later on in my studies, so I am much farther in my math degree.

When talking with the instructor about a topic research, I mentioned I would rather something more mathematical, and we came upon Real-space Green's function theory of electrical structure.

Now my question is...what exactly is this? I know what Green functions are and their uses in PDEs. But what should I be looking into?

That's the part I know. It's a method for solving inhomogeneous differential equations.

I'm just not sure on what the electrical structure part means. That's more quantum stuff, right? What falls under "electrical structure?"

Don't think so. That's the way he worded it and called it, not me. I know Green's theorem is used to help solve inhomogeneous diff eqs, and can be used with the wave equation. When I google "theory of electrical structure" I get a lot of quantum stuff. I was expecting E&M to come up, but I am much more excited to do quantum applications. But "theory of electrical structure" is pretty broad. I don't know what topics there are that I can cover

>>	Anonymous Thu Jan 20 03:08:23 2011 No.2380032 >>2380015 I believe that by "electrical structure", they mean the motion and positions of electrons around a positive nucleus. See: http://arxiv.org/PS_cache/physics/pdf/0009/0009018v2.pdf I hope your dirac notation is up to scratch.

Most welcome, I'm actually a physics/applied maths double major too, although I chose to do applied maths at the end (opposite to you).

This is just a guess, but there may be uses of Green's Function in Solid State Physics (ie study of the electronic structure on material surfaces).
