For an example, from Ref., when N=10000 and the frequency of the harmonic trap ω=100/s, the bandwidth Ebw of the ground bands of R 87 b and N 23 a condensates are 4× 10-9 and 1.7× 10-8 meV, respectively. Accordingly, when T= 10-6 K, the ratio of the probabilities of staying in the highest and the lowest levels of the band e- Ebw /kT is 0.95 (Rb) or 0.82 (Na). When T= 10-3 K, the above two values become 0.99995 (Rb) or 0.99980 (Na).
