Abstract
Abstract A number of phenomena are discussed which appear in the polar phase of nonequilibrium ferroelectric (systems without an inversion center): bulk photogalvanic effect, polar thermo-EMP and thermoconductivity and some others, in particular, these phenomena have anomalous and different values along and against to the spontaneous polarization velocity of distribution and damping of the electromagnetic and sound waves. All of them are connected with the specific character of the electronic quantum transitions in the system with off-diagonal long range order (ODLRO) and they can be united under one term “coherent effects”.
