Query: On the ground-state wave function of the one-dimensional polaron in the
  strong-coupling limit   We consider the one-dimensional Froehlich polaron localized in a symmetric
decreasing electric potential. It is known that the non-linear Pekar functional
corresponding to our model admits a unique minimizer. In the strong-coupling
limit, we show that any approximate ground-state wave function of our model-
after integrating out its phonon modes- converges in the weak sense to this
unique minimizer.
