I've been under the impression that "solid state physics" is just an older term for what is now commonly called "condensed matter physics," i.e. that they refer to essentially the same types of physics. Is that actually true? (Or, perhaps I should say, is that view also common in the wider world outside my department?)
I see that we have both a
solid-state-physics tag and a
condensed-matter tag. If the terms are actually synonymous, I'll merge the tags together; otherwise I think we should get started writing tag wikis that distinguish them.
