It's not that I don't trust you but I have been trying to sort of check your facts on this and I can't find anything.
I've posted numerous links that explain what I'm saying

. If you're doing a 'search' function in your browser, you won't find it; it's in the text in as small a detail as the '
r' in Ψ(
r,t) in the time-independent Schrödinger equation (the Wikipedia article to which both you and I cited) - that '
r' denotes spacial coordinates, which don't arbitrarily truncate. The wavefunction - in this case, the position-space wavefunction - describes the probability that a particle exist at any given point in space. This is what is meant by Ψ(
r,t).
Let me see if I've got what you're saying straight: entanglement is no mystery for physicalism, it's explained by physical interactions via Schrodinger's equation.
That depends on what you mean by 'mystery' - the stock market is a mystery to me, but I daresay it's physical.
I'd also like a definition of 'physicalism' before I commit to it. Common definitions are maddeningly incomplete, so hopefully you can be more exhaustive in your definition.
If that is what you're saying please post a link to an article or paragraph that describes this, with the main focus of the article or paragraph being "how Schrodinger's equation explains entanglement via physical interactions."
I can't help but feel you're tying arbitrary conditions onto this request - an article giving a general and exhaustive overview of the equation (such as the
Wikipedia article)
does contain the information you seek. Ultimately, the Schrödinger equation describes how a physical systems, mathematically described by their wavefunctions, evolve in space and time. Entanglement is an inescapable consequence of how wavefunctions behave, but it doesn't suddenly become non-physical. The wavefunctions persist over all of space, changing over time, and the two entangled particles exist as a superposition of these wavefunctions, which collapse at the point of measurement (for however you interpret wavefunction collapse).
Nevertheless, obeying your arbitrary restrictions, this
article focus on the Schrödinger equation and quantum entanglement.
I recommend
this textbook; I have my own copy, if you want chapter references.
The word physicalism isn't working because it includes physical forces. So rather than talk about what is physical and what is nonphysical, I put it like this: Can entanglement be explained (rather than described) by processes that happen in a self existent universe or does it require something outside of our physical universe?
Yes: observation-induced wavefunction collapse.
You are saying it doesn't require anything outside of our universe. That is what I'm interested in. How it explained in terms of physical forces within our universe?
It isn't. The physical forces aren't involved with the phenomenon of quantum entanglement.
