Coupled motion and mechanics with cooperative atoms; 2. Sympathetic cooling and applications of laser tweezers in large-scale quantum computing. In 1, we investigate the dynamics on cooperatively coupled atoms subject to light pressure taking into account their dipole-dipole interaction and Doppler cooling. In 2, we model sympathetic cooling in a large ion array and look at the distribution of the kinetic energy or temperature. We further investigate the application of optical tweezers, which introduces local traps and raising frequencies, and how they help stabilize a long array of ions for large-scale quantum computing.協同效應超幅射雷射冷卻偶極偶極交互作用cooperative effectssuperradiancelaser coolingdipole-dipole interaction多體協同性理論於量子介面與冷卻之應用研究
