Delocalization of vibrational modes caused by electric dipole interaction

The electric dipole interaction of vibrational modes destroys their localization. Real-space renormalization is constructed for the process of delocalization. The renormalization-group equation for the distribution of dipole parameters is similar to the Boltzmann kinetic equation. Conservation laws are found and an H theorem is proven. Stationary distributions form a six-parameter manifold of fixed points. The two-point dynamical correlation function has the form t^-1F (t^-1/3r), where F (x) is a universal function.
