Some people told me
Stop it, please.

You know "some people told me" is not an acceptable reference here.

Are those individual particles or what?
Or what? What do you means by "particle"? Like "a particle or dust"? They certainly are not individual atoms, since the paper comes right ouit and says they aren't.

I just read the link, and it said the vortex lattices are magnetic fluxes. Sorry for asking without reading the link first. But another question, is it possible to detect individual atoms while they are all in BEC state?

According to this article https://www.livescience.com/54667-bose-einstein-condensate.html, it said "What the two found was that ordinarily, atoms have to have certain energies — in fact one of the fundamentals of quantum mechanics is that the energy of an atom or other subatomic particle can't be arbitrary. This is why electrons, for example, have discrete "orbitals" that they have to occupy, and why they give off photons of specific wavelengths when they drop from one orbital, or energy level, to another. But cool the atoms to within billionths of a degree of absolute zero and some atoms begin to fall into the same energy level, becoming indistinguishable."

I think by indistinguishable, they mean the atoms in Bose-Einstein condensates (BEC) states can't be detected as individual atoms. Not sure but please tell me if they mean otherwise.

But in these images https://calderup.wordpress.com/2010/08/18/superatomic-circus/#more-1556 and https://www.researchgate.net/figure...trapped-in-an-optical-lattice_fig18_322735643 we can actually see individual atoms in BEC states. Are there any other images that show individual atoms in BEC states? If these images indeed show individual atoms in BEC states, that means it is actually possible to detect discrete individual atoms in BEC states.
