A tale of two condensates: the odd "Bose - Einstein" condensation of atomic Hydrogen

The recent report of the observation of Bose-Einstein condensation in atomic Hydrogen, characterized by an "anomalous" density spectrum, is shown to be in agreement with the prediction of the existence of two condensates for temperatures lower than a well defined temperature (which for Hydrogen is $ 105~ \mu K $), based on the QED coherent interaction in a gas of ultracold atoms at a density $n > n_0 (n_0=(1/\lambda)^3, \lambda$ being the wave-length of the e.m. modes resonantly coupled to the Hydrogen atoms)
