The Paradox of Bose-Einstein Condensation
arXiv:2307.11743
Abstract
The paradox of Bose-Einstein condensation is that phenomena such as the -transition heat capacity and superfluid flow are macroscopic, whereas the occupancy of the ground state is microscopic. This contradiction is resolved with a simple derivation for ideal bosons that shows Bose-Einstein condensation is into multiple low-lying states, not just the ground state.
