1: 当初の計画以上に進展している
理由
Our results are better than initially expected. This is evidenced by the fact that referees from the very top journals (Science, Nat. Photon., PRL, Physics Reports, etc.) have been enthusiastic about the quality and significance of our research results.
We plan to continue research in the same general area. Instead of providing another list of projects, let me focus on one example, accepted in Nat. Phot.
Optomechanically induced stochastic resonance and chaos transfer between optical fields: Chaotic dynamics has been reported in many physical systems and has affected almost every field of science. Chaos involves hypersensitivity to the initial conditions of a system and introduces unpredictability into its output. Thus, it is often unwanted. Interestingly, the very same features make chaos a powerful tool to suppress decoherence, achieve secure communication and replace background noise in stochastic resonance; a counterintuitive concept that a system's ability to transfer information can be coherently amplified by adding noise. Here, we report the first demonstration of chaos-induced stochastic resonance in an optomechanical system, as well as the optomechanically mediated chaos transfer between two optical fields such that they follow the same route to chaos. These results will contribute to the understanding of nonlinear phenomena and chaos in optomechanical systems, and may find applications in the chaotic transfer of information and for improving the detection of otherwise undetectable signals in optomechanical systems.

| 今後の研究の推進方策 |
We plan to continue doing interdisciplinary theoretical and computational investigations at the intersection of quantum optics, atomic physics, and condensed matter physics in the context of engineered quantum micro- and nano-electronics. Semi- and super-conducting electrical devices provide an unprecedented platform for experimentally realizing controlled and designable quantum systems. With these devices it is possible to create circuit analogues and simulations of quantum phenomena from a wide range of fields of physics. We will also continue investigating other related topics at the interface with optics, which we pioneered in our group. Interdisciplinary research of this type (done in collaboration with experimental groups) will continue catalyzing discoveries and make new connections between various subfields of physics, thus paving the way to future quantum technologies.
