Stochastic Resonance and Nonlinear Response by NMR Spectroscopy
arXiv:quant-ph/0001095 · doi:10.1103/PhysRevLett.84.5466
Abstract
We revisit the phenomenon of quantum stochastic resonance in the regime of validity of the Bloch equations. We find that a stochastic resonance behavior in the steady-state response of the system is present whenever the noise-induced relaxation dynamics can be characterized via a single relaxation time scale. The picture is validated by a simple nuclear magnetic resonance experiment in water.
