A search on the arxiv number of the paper didn't turn up any other threads here on PF. So I think we're good.

It's beyond my depth but I saw a recent paper Strings from almost nothing that sounds interesting to me. If this has been discussed...

What I understood from...

I agree. In philosophy any statement X may be argued as well as any statement not X with no acceptable means of determining which, if...

Clearly, I can’t. Which is also my point. Neither has anyone else. I’m also not the one employing such a term.

Ah, ok. This references several papers by Jacob Barandes, whose work has been discussed in previous PF threads. This one is probably the...

So, dressing the same physics up in a different mathematical framework definitely can have value. However, how is this mathematical...

And, such a tractable problem at that.

Here's a nice review paper from 2023: Proton decay. You can probably find more up-to-date info by using Google Scholar to search for...

The quantum computers use networks of entangled qubits.

Yet, both ##\nu## and ##E## are continuous quantities unless I’ve missed a memo.

This is not what you asked for but looks like a good resource. https://arxiv.org/pdf/1312.3824

One is always free to change gauges. One is not free to violate charge conservation. Beyond that, I have no idea what you’re trying to...

The EOM you quote conserve charge, ##\partial_\mu J^\mu =0##. You then violate charge conservation with your assumption, ##K^\mu =...

I am studying the contact angle of a sessile droplet (water and alcohol mixtures) on both horizontal and inclined surfaces. I capture...
