Helium becomes a superfluid at about 2k. (a) (4 pts) assuming it is a perfect bose condensate of s = 0 atoms, with a number density of 2.11×1028 atoms/m3 in the he liquid, and mass for the he atom of 4.0 u, estimate the bose-einstein condensation or superfluid transition temperature using eq. (10.45). differences with the observed result are due to interactions between he atoms. (b) (4 pts) the next lightest noble gas is neon. estimate the temperature at which neon should become a superfluid, using a number density of 3.58×1028 atoms/m3 in the liquid phase, and an atomic mass of 20.1 u. (c) (2 pts) can you guess why neon doesn’t become a superfluid?
