Can we have a tag for questions related to atomic, molecular and optical physics? I'd suggest "AMO-Atomic Molecular and Optical Physics".
On a related note, how many tags we have here match APS subject tags? Perhaps it would be a good idea to include APS subject classification?
I don't know if this specific question has been brought up before. I am just too lazy to look it up. Sorry. :]
Edit: APS = American Physical Society. I mean take a look at Phys.Rev.Letters or Europhysics Letters and see how editors categorize subfields. Perhaps we could simply include that categorization as tags?
AMO is pretty much a catch-all phrase for laser cooling, ion trapping, optical lattices, BEC studies, Atom Magnetometry and tons more.
