Squeezing of quantum fluctuation plays an important role in fundamental quantum physics and has marked influence on ultrasensitive detection. We propose a scheme to generate and enhance the squeezing of mechanical mode by exposing the optomechanical system to a non-Markovian environment. It is shown that the effective parametric resonance term of mechanical mode can be induced due to interaction with the cavity and non-Markovian reservoir, thus resulting in quadrature squeezing of the mechanical resonator; jointing the two kinds of interactions can enhance the squeezing effect. Compared with the usual Markovian regime, we can obtain stronger squeezing, and, significantly, the squeezing can approach a low asymptotic stable value.
量子涨落的挤压在基础量子物理学中起着重要作用，并对超灵敏检测产生了显著影响。我们提出了一种方案，通过将光机械系统暴露于非马尔可夫环境中，来产生和增强机械模式的挤压。结果表明，由于与腔和非马尔可夫储层的相互作用，可以诱导机械模式的有效参数共振项，从而导致机械谐振器的正交挤压；结合这两种相互作用可以增强挤压效果。与通常的马尔可夫态相比，我们可以获得更强的挤压效果，并且，重要的是，挤压可以接近一个低的渐近稳定值。
