Causation, Mind, and Psionics

[Neo-Scholastic]

First of all, I want to see links for this, because I'm pretty dubious that these results are generally accepted

Not really generally accepted. Controversy still exists. I may have overstated the case. That said, I often come across quotes by skeptics that accept the findings but not the conclusions. Here is one example:

As for the rest, I have ordered scans of the articles from the library.

Second, I'm not sure why you are calling probabilistic cause efficient cause.

I'm trying to preserve the distinction between the modern use of the word 'cause' and the other 4 types of cause. At the same time, I am saying that probabilistic cause performs the same function as efficient cause as understood by the Scholastics.

Is it considered scientific fact? ...the pixelation of timespace ...

I would say it is. The Plank-scales for time and space represent the smallest possible quantity of either one. Space and time at that scale cease to be dividable. That indivisablity gives the universe a maximum resolution so to speak.

It should be noted that quantum mechanics is entirely deterministic.

Before you can assert that something is deterministic you must have a philosophy of causation in place that supports it. Hence the OP. A purely mechanistic understanding of cause would support what you say about quantum mechanics, though not decisively. Yours would be one interpretation of quantum phenomena.
