| Outline of Final Research Achievements |
A novel hybrid simulation based on the coupled classical and quantum theories has been developed. Various light-matter interactions were investigated by the proposed technique considering currents obtained by wave functions and tunnel effect.
Performing the hybrid simulation, next generation technology of magnetic recording was studied. The proposed ultra-fast and high-density method is based on all-optical magnetic recording using nano antennas together with particulate recording media. In our system, the magnetic recording speed is about 100,000 times faster than that for conventional methods and the recording density becomes over a few Tbit/inch2. The system possesses high robustness for changing the position of antennas and recording media. We also clarified the condition of generating localized circularly polarized light for realistic nano-antenna models whose shapes are perturbed considering fabrication process.
