It is well known that in dynamical systems governed by long-range forces, the secular evolution of the system is driven predominantly by collective effects. In the current paper, we report the discovery of such a collective dissipation process induced by a self-sustained spiral density wave, which leads to important secular evolution effects in spiral galaxies.
