An initially strongly localized TIP state expands almost ballistically up to $\\xi_1$. The expansion of the TIP wave function beyond the distance $\\xi_1 \\gg 1$ is governed by highly connected Fock states in the space of noninteracting eigenfunctions. The resulting dynamics is subdiffusive, and the second moment grows as $m_2 \\sim t^{1/2}$, precisely as in the strong chaos regime for corresponding nonlinear wave equations.
