Fig. 1: The classical Fisher information (FC), in the case of an infinitely narrow momentum width source of atoms, is plotted (black curves) as a function of the wave vector of atomic cloud (The dimensionless wave vector, \({\tilde{k}}_{i}={k}_{i}/\kappa\), where \(\kappa =\sqrt{(2m{V}_{1}/\hslash )}\) is the wave vector corresponding to the characteristic energy of the first barrier). | npj Microgravity

The red curves illustrates the variation in transmission coefficient T. Here, κ is kept constant and ki is varied for different cavity lengths d. The peaks in FC are shown to correspond to the transmission resonant peaks. The optimum \({\tilde{k}}_{i}\) that gives the highest value of FC can be calculated from this plot. It shows that the optimum FC and \({\tilde{k}}_{i}\) varies with cavity length.
