[quote]It is nevertheless already clear from the above data that entangled states are favored in the stoichiometric regime. The existence of a low temperature phase in which all the deuterons cohere in a mesoscopically entangled state is hence strongly indicated.[/quote] The only state of matter where the “low temperature phase in which all the deuterons cohere” is hydrogen formed as Rydburg matter. Forming hydrogen in a fermionic condensate is near impossible in any other way.
