Outline of Annual Research Achievements

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.
