Nonlinear modes of a macroscopic quantum oscillator

Alexander, Tristram J; Turitsyn, S; Kivshar, Yuri


We consider the Bose-Einstein condensate in a parabolic trap as a macroscopic quantum oscillator and describe, analytically and numerically, its collective modes - a nonlinear generalisation of the (symmetric and antisymmetric) Hermite-Gauss eigenmodes of a harmonic quantum oscillator.
