I can't say I'm familiar with that part of OF, or OF in general, but that was supposedly the intent behind OF originally, a place for fans of whatever. That's the origin story anyway. They also supposedly tried to downplay the sexual side, and Bonnie Blue did at least eventually reach the limits of their ToS there.
Neil deGrasse Tyson does have a fanbase. No idea if he's on OF, and I wouldn't say his area of expertise is specifically quantum physics, but he does have the vibe for it. I could also see him wearing a jacket with elbow patches.

If he doesn't have a quantum physics OF, this will have to tide you over.
