Conformal symmetry and the nonlinear sigma model

We present an analytical description of the dynamics of the width of the wave packet for a class of nonlinear sigma models coupled to quarks and characterized by the dynamical O(2, 1) conformal symmetry.As an application we study the dynamical instabilities of the rotating as well as non-rotating Bose-Einstein condensates.
