Query: Centrifugal Effects in a Bose-Einstein Condensate   Single particle states in the atomic trap employing the rotating magnetic
field are found using the full time-dependent instantaneous trapping potential.
These states are compared with those of the effective time-averaged potential.
We show that the trapping is possible when the frequency of the rotations
exceeds some threshold. Slightly above this threshold the weakly interacting
gas of the trapped atoms acquires the properties of a quasi-1D system in the
frame rotating together with the field. The role of the atom-atom interaction
in changing the ideal gas solution is discussed. We show that in the limit of
large numbers of particles the rotating field whose angular frequency is
appropriately modulated can be utilized as a driving force principally for the
center of mass motion as well as for the angular momentum $L = 2$ normal modes
of the Bose condensate. A mechanism of quantum evaporation forced by the
rotating field is analyzed.
