Narrow band noise at finite temperature gradients

We consider the collective motion of the charge density wave in systems with a weak space dependence of temperature by analysing numerically the Gor'kov's model. It is shown that in such conditions the phase slips can be generated in the bulk, dividing so the system into a finite number of dynamically correlated domains. This causes the splitting of fundamental peaks in the narrow band noise spectrum. With the increase of temperature gradient the system passes through bistable ranges in which the number of domains increases by one.
