摘要:

我们周围的大部分物理世界都可以用热力学平衡中的谐振子来描述。同时,振子远离平衡态的行为在现代物理学的许多方面都很重要。在这里,我们调查的谐振系统受到的内在非线性和几个驱动力的组合之间的基本相互作用。我们已经构建了一个可控的和强大的实现这样一个系统,使用宏观双箝位字符串。我们实验观察到一个迄今为止看不见的双重滞后的振幅和相位的谐振器的响应函数,并提出了一个理论模型,是在很好的协议与实验。我们的工作提供了一个透彻的理解的双滞回响应,通过对称性破缺的参数相态,阐明了选择标准之间的过渡稳定的解决方案。我们的研究激发了从超灵敏力检测到低能量计算存储单元的应用。

英文摘要:

Much of the physical world around us can be described in terms of harmonic oscillators in thermodynamic equilibrium. At the same time, the far from equilibrium behavior of oscillators is important in many aspects of modern physics. Here, we investigate a resonating system subject to a fundamental interplay between intrinsic nonlinearities and a combination of several driving forces. We have constructed a controllable and robust realization of such a system using a macroscopic doubly clamped string. We experimentally observe a hitherto unseen double hysteresis in both the amplitude and the phase of the resonator's response function and present a theoretical model that is in excellent agreement with the experiment. Our work provides a thorough understanding of the double-hysteretic response through a symmetry breaking of parametric phase states that elucidates the selection criteria governing transitions between stable solutions. Our study motivates applications ranging from ultrasensitive force detection to low-energy computing memory units.
