Abstract
The ground state and low-lying collective modes of Bose-Einstein condensate (BEC) of atoms with arbitrary spin in a magnetic field is studied using Bogoliubov's model for weakly interacting Bose gas. The equation for vectorial order parameter valid at temperature Tâ0 is derived and its specific solution is found. This solution corresponds to the formation of BEC of atoms with a definite spin projection onto direction of magnetic field. We study the thermodynamic stability of the found ground state and obtain the expressions for low-lying collective modes.
