论文摘要
在由光腔组成的混合微粒系统中,我们在分析和数值上都证明了连接到低温热浴的移动镜,在随机原子通量和光学机械腔之间的某些相互作用时间上,真空音子捕获状态是产生的。此外,在用独立的声子和光子热浴的主方程的接近下,我们表明声子和光子的捕获是在相同的相互作用时间内实现的。结果还表明,通过增加空腔振荡器耦合,除了捕获状态外,一个可能会产生连贯的声子状态。在同一混合系统中,但现在连接到挤压的声子储存库,可以设计一个声子封锁效果。此外,我们确定捕获效应和阻断效应之间的互连,尤其是在接近真空诱捕状态的情况下,当系统与弱挤压的声子储层连接时,可以实现强烈的声子封锁。
In a hybrid micromaser system consisting of an optical cavity with a moving mirror connected to a low temperature thermal bath, we demonstrate, both analytically and numerically, that for certain interaction times between a random atomic flux and the optomechanical cavity, vacuum phonon trapping states are generated. Furthermore, under the approach of the master equation with independent phonon and photon thermal baths, we show that the trapping of the phonons and photons is achieved for the same interaction times. The results also indicate that by increasing the cavity-oscillator coupling one may generate a coherent phonon state aside from the trapping states. Within the same hybrid system, but now connected to the squeezed phonon reservoir, a phonon blockade effect can be engineered. Moreover, we identify an interconnection between the trapping and blockade effects, particularly if one approaches the vacuum trapping state, strong phonon blockade can be achieved when the system is connected with a weakly squeezed phonon reservoir.
