Abstract

It is shown that for systems with a periodic potential, the flux is very sensitive to the strength of additive and/or multiplicative noise. Multiplicative noise becomes important when its strength is of order the barrier height, and it provides a means of additional control of the flux (voltage-current characteristics for a Josephson junction). In addition to a numerical analysis, the cases of weak and strong additive noise have been considered analytically.
