Thus, for one atom, we have P00 (t) = 1/2 and, for two atoms, we have P00 (t) = 3/8. √ In the case of a large number of atoms A 1, using the Stirling formula n! ∼ 2nπ nn e−n , we obtain P00 (t) ∼ √ 1 Aπ −→ 0 that is, the system with a large number of atoms has a greater probability of becoming excited. 35 36 2 Atomic Dynamics Next, we calculate the probability P01 (t) of a transition from the ground state to the ﬁrst excited state. k! |k, A A−k ! we obtain | k|eαS+ |0 |2 = |α|2k k! 2 | k|Sk+ |0 |2 = A!
