项目摘要

a) Optomechanical system's dynamics controlled by light-induced force (LIF):-stability conditions for oscillator and exactly general coupling G have been clarified. This G shows a collinear dependence on the cavity decay rate (kappa) preventing the cooling in good cavity limits and approximates to kappa for much smaller kappa. The fifth-order multistability in these optomechanical systems is figured out.-minimum effective temperature T_eff shifts to low-kappa region and locates around kappa= 0.03 X the mechanical frequency. T_eff of about several tens of mK is possible and a quantum number of 0.01 can be obtained (the oscillator is 99% in the ground state). This shows the possibility of using solely the LIF in ground-state cooling with very low power and opens a way to apply it to the quantum communication.b) Examining low-dimensional system's photoluminescence:Suitable dispersion for polaritons pumped by surface acoustic wave (SAW) is clarified to examine energy relaxation (modulation of dispersion by SAW facilitates this process). Time-dependent quantities (occupation number, high-order correlation, decrease of linewidth) will be examined to confirm the polariton lasing (vs. photon lasing). Such a simpler mechanism is promising for high temperature polariton lasing.c) Plasmonic energy transfer using nano hole array (NHA): LIF for the trapping of viruses at the edge of NHA with random sharp metallic nanostructures was evaluated and it was clarified that virus can be attracted toward the high-sensitivity position with large peak shift of extraordinary optical transmission.

a）光生力（LIF）控制的光机系统动力学：阐明了振子的稳定性条件和广义耦合G。该G示出了对腔衰减速率（kappa）的共线依赖性，从而防止在良好的腔极限中冷却，并且对于小得多的kappa，该G近似于kappa。计算了这些光机系统的五阶多稳态。最低有效温度T_eff向低kappa区移动，位于kappa= 0.03 ×机械频率附近。T_eff可以达到几十mK，量子数为0.01（振荡器99%处于基态）。这表明了在基态冷却中仅使用LIF的可能性，具有非常低的功率，并打开了一种方法，将其应用到量子通信。B）检查低维系统的光致发光：适当的色散由表面声波（SAW）泵浦的极化激元澄清检查能量弛豫（由SAW色散的调制促进这一过程）。将检查与时间相关的量（占据数、高阶相关、线宽减小）以确认极化激元激光（与光子激光相比）。这种更简单的机制对于高温极化激元激光是有希望的。c）使用纳米孔阵列（NHA）的等离子体能量转移：评估了用于在具有随机尖锐金属纳米结构的NHA边缘处捕获病毒的LIF，并且澄清了病毒可以被吸引向具有极大的非寻常光透射峰位移的高灵敏度位置。
