Symmetry breaking based detectors are a wide and relatively unexplored class, which includes, among others, stochastic-resonance based detectors [1-3], and many more.
In this communication we discuss a possible basic paradigm, where the observable is the distribution of (real) zeros of random polynomials whose coefficients are the time samples of a signal+noise mixture, and the signal, whose possible presence has to be detected, has a known adiabatically evolving angular frequency.
Possible application to gravitational wave detection from pulsars and coalescing binaries is suggested and preliminarily discussed.
