comment What is the largest number of bosons placed in a BEC?
Do you mean Streed et al. is likely to be the highest atomic BEC? How high do you expect for quasi-particles, and who should I look at?

comment What is the largest number of bosons placed in a BEC?
I am pretty sure they are in number eigenstates for massive bosons like atoms. That's not even super important though, as coherent States are strongly peaked around a certain number for large N.

comment Is the ground state of a QFT always a pure state? And excited states are mixed?
Said another way: the important distinction for getting area laws rather than extensive/volume scaling isn't so much pure vs. mixed, but rather local vs. random.

comment Is the ground state of a QFT always a pure state? And excited states are mixed?
The fact that the pure state under consideration is the ground state of a local Hamiltonian is crucial. A random pure state taken from the Hilbert space according to the Haar measure has extensive entropy (i.e. increasing proportional to volume until, of course, you reach the point where the region considered becomes as large as half the total system, at which point the the entropy scales like the volume of the complement region). This is Page's conjecture, later proved, and is a consequence of the concentration of measure. arxiv.org/abs/gr-qc/9305007

revised A step in the derivation of the magnetic moment of the electron in Zee's QFT book
Fix typo in title. It's "magnetic moment" not "magnetic momentum", as confirmed by phrase used in the body.
