Bose–Einstein condensation and heat capacity of spin-polarized atomic hydrogen

The condensation fraction, transition temperature, and heat capacity per particle have been calculated for the spin-polarized atomic hydrogen system using the static fluctuation approximation (SFA). The transition temperature has been found to be greater than that for the noninteracting gas, which is consistent with dilute systems results. The heat capacity has a cusp at the transition temperature similar to liquid helium-4. The results obtained indicate that superfluidity behavior occurs in spin-polarized atomic hydrogen system.
