FWIW I’ve used LLMs to invent new things. Not super groundbreaking fundamental research, but they were able to use physics to design a device that didn’t exist yet, from first principles.
Okay, so rereading it as pedantically as you seem to insist:
You "invented" ("Designed") a "device" "using physics", and nobody has designed that "device" before, making it novel.
"From first principles" is a fun statement because people like Aristotle also thought they were reasoning from "first principles" and look how far it got them. The entire point of science is that "first principles" are actually not something we have access to, so we should instead prioritize what literally happens and can be observed. It's not possible as far as we know to trick mother nature into giving us the answer we want rather than the real answer.
Did you ever actually build or test this "device"?
