BOSE CONDENSATION OF IDEALIZED SPIN-POLARIZED ATOMIC-HYDROGEN IN EQUILIBRIUM
The published version is at http://prl.aps.org/abstract/PRL/v44/i21/p1420_1
A model of spin-polarized hydrogen (H↑) is treated in which interactions between atoms are neglected while the single-atom Zeeman and hyperfine interactions are treated exactly. These magnetic terms in the Hamiltonian are found to affect substantially the Bose-Einstein condensation and the various thermodynamic variables. Computations are discussed of the condensation temperature, condensate density, and specific heat in order to indicate how changes in magnetic field strength might be expected to affect future measurements on this quantum system.
