Hey guys,

I have to admit that my knowledge of this stuff is probably quite lacking in comparison to most other people's but I was wondering if anyone had some resources I could use to look into regarding nonlocality?

From what little I do know about Quantum Mechanics is that Einstein had a beef with its probabilistic nature and insisted that there was a third particle involved which has since been disproved. I've been trying to look into possible nonlocal explanations for quantum phenomenon such as what happens in the quantum eraser experiment and was wondering if anyone has any knowledge of work being done with this or if there are any currently accepted theories?

The currently accepted theory is quantum mechanics

Don't know what you mean by "a third particle involved", but there's been more papers written on quantum nolocality than you can shake a stick at. I share your curiosity about this and can only suggest that you utilize the available internet resources. Search in Physics Forums, Google, Yahoo, arxiv.org, Wikipedia, Stanford Encyclopedia of Philosophy, etc. etc. You'll find enough material to keep you busy for years.

Thanks for the tip.

As you can tell I'm pretty new to all of this and am just barely starting to get my head wrapped around a few things. But it seems to me that anytime someone tries to mention a cause and effect relationship of the random nature of QM people tend to dismiss it as nonsense or impossible. I've only recently stumbled upon a few ideas for nonlocal ideas but I have no idea how valid any of these ideas (although I don't know if most physicists really do either).

Also, by 'third particle involved' I was trying to reference the EPR paradox... which I just reread and apparently does not necessarily involve a 'particle'.
 
Not an expert in QM. AFAIK, Schrödinger's equation is quite different from the classical wave equation. The former is an equation for the dynamics of the state of a (quantum?) system, the latter is an equation for the dynamics of a (classical) degree of freedom. As a matter of fact, Schrödinger's equation is first order in time derivatives, while the classical wave equation is second order. But, AFAIK, Schrödinger's equation is a wave equation; only its interpretation makes it non-classical...

Is it possible, and fruitful, to use certain conceptual and technical tools from effective field theory (coarse-graining/integrating-out, power-counting, matching, RG) to think about the relationship between the fundamental (quantum) and the emergent (classical), both to account for the quasi-autonomy of the classical level and to quantify residual quantum corrections? By “emergent,” I mean the following: after integrating out fast/irrelevant quantum degrees of freedom (high-energy modes...
