    "abstract": "Multistep Bose-Einstein condensation of an ideal Bose gas in anisotropic\nharmonic atom traps is studied. In the presence of strong anisotropy realized\nby the different trap frequency in each direction, finite size effect dictates\na series of dimensional crossovers into lower-dimensional excitations. Two-step\ncondensation and the dynamical reduction of the effective dimension can appear\nin three separate steps. When the multistep behavior occurs, the occupation\nnumber of atoms excited in each dimension is shown to behave similarly as a\nfunction of the temperature.",
