Bose-Einstein condensation and successive phase transition.
The field of Bose-Einstein condensation of atomic gas has continued to progress rapidly./1/
We studied the successive phase transitions in ferroelectrics in the mid 1980 /2,3/
We suggested that molecules of this substances had the quantum states of energy about kT.
Then we suggest, that with the change of temperature there was Bose-Einstein condensation,
whereby a macroscopic number of identical molecules occupy the same quantum state /2-5/.
Theoretically was predicted the possibility of Bose-Einstein condensation in this substances
and explained the successive phase transitions/2-5/.
