フォノンの光変調による電子励起状態の間接的制御の理論

a)光致力（LIF）控制的光机械系统动力学：阐明了振荡器和精确一般耦合G的稳定性条件。这个G显示了对腔衰减率（kappa）的共线依赖，在良好的腔限制下防止冷却，并且近似于kappa。研究了这些光力学系统的五阶多重稳定性。-最低有效温度T_eff向低kappa区域移动，位于kappa= 0.03 X机械频率附近。大约几十个mK的T_eff是可能的，并且可以获得0.01的量子数（振荡器99%处于基态）。这显示了在极低功耗的基态冷却中单独使用LIF的可能性，并为将其应用于量子通信开辟了一条道路。b)检测低维系统的光致发光：澄清了表面声波（SAW）泵浦极化子的合适色散，以检测能量松弛（SAW调制色散有助于这一过程）。时间相关的量（占用数，高阶相关，线宽减少）将被检查，以确认极化激子激光（相对于光子激光）。c)利用纳米空穴阵列（NHA）的等离子体能量转移：利用随机尖锐金属纳米结构捕获NHA边缘的LIF，明确了病毒可以被吸引到高灵敏度位置，具有非凡光传输的大峰移。

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.
