Bourgain. We also study the regularity properties of weak-* limits of sequences of densities of the form $|e^{it\\Delta}u_{n}|^{2}$ corresponding to highly oscillating sequences of initial data $(u_{n})$. We obtain improved regularity properties of those limits using previous results by N. Anantharaman and F.
