标题： Phase Stochastic Resonance in a forced nano-electromechanical oscillator

摘要： 随机共振是一种通常在一维、振幅调制、双稳态系统中观察到的普遍现象。我们通过实验证明，在受迫纳米机电膜的二维响应中出现了相位随机共振，通过证明添加相位噪声可以增强微弱的相位调制信号。 基于一个一般的受迫杜芬振子模型，我们实验和理论上证明了相位噪声以乘性方式起作用，导致重要的物理后果。 这些结果可能为纳米机械振荡器中的相位噪声计量或相干信号传输应用开辟有趣的前景。 此外，由于我们方法的普遍性，它可能适用于各种系统。 显示英文摘要

摘要： Stochastic resonance is a general phenomenon usually observed in one-dimensional, amplitude modulated, bistable systems.We show experimentally the emergence of phase stochastic resonance in the bidimensional response of a forced nano-electromechanical membrane by evidencing the enhancement of a weak phase modulated signal thanks to the addition of phase noise. Based on a general forced Duffing oscillator model, we demonstrate experimentally and theoretically that phase noise acts multiplicatively inducing important physical consequences. These results may open interesting prospects for phase noise metrology or coherent signal transmission applications in nanomechanical oscillators. Moreover, our approach, due to its general character, may apply to various systems.
