二维q态钟模型中的随机共振

Stochastic resonance in the two-dimensional q-state clock models

Hye Jin Park, Seung Ki Baek, Beom Jun Kim

摘要:

数值研究了二维q态时钟模型在弱振荡磁场作用下q = 2 ~ 7的随机共振现象。在平均场的情况下,我们观察到双共振峰,但详细的响应强烈地依赖于场调制的方向为q >= 5的准液相出现。我们解释这种行为的自由能景观的二维磁化平面。

英文摘要:

We numerically study stochastic resonance in the two-dimensional q-state clock models from q = 2 to 7 under a weak oscillating magnetic field. As in the mean-field case, we observe double resonance peaks, but the detailed response strongly depends on the direction of the field modulation for q >= 5 where the quasiliquid phase emerges. We explain this behavior in terms of free-energy landscapes on the two-dimensional magnetization plane.
