Query: On stabilization of small solutions in the nonlinear Dirac equation with
  a trapping potential   We consider a Dirac operator with short range potential and with eigenvalues.
We add a nonlinear term and we show that the small standing waves of the
corresponding nonlinear Dirac equation (NLD) are attractors for small solutions
of the NLD. This extends to the NLD results already known for the Nonlinear
Schr\"odinger Equation (NLS)
