Noise-Induced Dynamics in Bistable System
Such a bistable system
can operate as a detector when a sufficiently strong external force -- a signal -- nudges the ball over the barrier into the second well (analogous to switching the direction in which light travels in a ring laser).
This is why real samples do not exhibit linear responses or infinite susceptibility; instead, they behave as bistable systems
that switch between different states of internal alignment at critical values of the external field (see Appendix).
