| Outline of Final Research Achievements |
In this proposal, we have investigated electromagnetic response of novel metamaterial Intrinsic Josephson Junction Quantum Metamaterial (IJJQM) which utilize intrinsic Josephson junctions in high-Tc superconductors. On the basis of a simple toy model for IJJQM, we found unique characteristics of quantum metamaterial such as the chaotic dynamics of the qubits and the lasing associated with correlated behavior of the qubits. We also clarified that the electromagnetic properties of intrinsic Josephson junctions are highly tunable by external local heating.
Through the above studies, we have constructed basic theory for electromagnetic response of IJJQM and showed that IJJQM is promising as a novel optical device in next generation.
