A magnetic system with a phase transition at temperature T(c) may exhibit double-resonance peaks under a periodic external magnetic field because the time scale matches the external frequency at two different temperatures, one above T(c) and the other below T(c). We study the double-resonance phenomena for the mean-field q-state clock model based on the heat-bath-type master equation. We find double peaks as observed in the kinetic Ising case (q = 2) for all q ≥ 4, but for the three-state clock…

Double resonance in the infinite-range quantum Ising model.

It is proposed that the double resonance peaks should be a generic feature of continuous transitions, for both quantum and classical many-body systems.

Anomalous response in the vicinity of spontaneous symmetry breaking

We propose a mechanism to induce negative AC permittivity in the vicinity of a ferroelectric phase transition involved with spontaneous symmetry breaking. This mechanism makes use of responses at low
