The Quantum Pontiff has a brief summary of the APS March meeting, and notes that
There are a lot of physicists. Even if you don’t count the particle and nuclear and gravitational physicist who have their own meeting. Oh, and they are easily identifiable walking down the street in New Orleans.
Perhaps we are, but there are even more of us, because the Division of Atomic, Molecular and Optical Physicists meets in May. (The Canadian version omits the Optical, so you have DAMP physicists up there. Tee hee.) Though it seems some of them showed in in N’awlins, from other summaries at nanoscale views where some cold-atom physics in optical lattices is mentioned. (third summary here)
