A non-exotic manifestation of this is the ordinary O_2 molecule. Because of the Pauli principle it is required to rotate (angular momentum = hbar) even in its ground state. More precisely: arbitrarily weak perturbations produce a time-dependent state because the ground state (in the absence of perturbations) is degenerate. -Veit
