摘要: Measurements of the charge-density-wave (CDW) response in ${\mathrm{TaS}}_{3}$ indicate that low-frequency polarization phenomena play an important role coupled ac-dc dynamics this system. A simple phenomenological model, based on capacitive coupling, is proposed to explain observed suppression dc threshold by a large-amplitude ac field, and also phase shift 90\ifmmode^\circ\else\textdegree\fi{} for low generated difference frequencies small-signal harmonic mixing below threshold.
