Outline
Our group aims to increase understanding of various quantum phenomena through observations using the world's-highest-brightness electron beam, and to explore the forefront of a new research field: quantum-wave science. At the same time, we aim to propose innovative materials and devices based on the principles of quantum mechanics by the combined effects of three factors: experimental, theoretical and observational. Through initiative elucidation of quantum phenomena emerging in the frontier scientific fields such as macroscopic quantum coherence, magnetism and semiconductors, we hope to bring about a Japan-originated new trend in scientific and industrial prosperity in the 21st century.
Research Teams
- Team Leader
- Franco Nori
We perform research in theoretical condensed matter physics, including quantum information processing, computational physics, transport phenomena (e.g., of vortices, electrons and grains), energy conversion and solar energy, as well as the dynamics of complex systems.
- Team Leader
- Jaw-Shen Tsai
Macroscopic quantum scattering has been in Josephson qubit-based researchobserved. A nearly perfect reflection, inelastic scattering (resonance fluorescence), Mollow triplet, electromagnetically induced transparency, Autler-Townes doublet, optical pumped population inversion, amplification by stimulated emission and other very rich physics were revealed.
- Team Leader
- Yoshichika Otani
The magnetic vortices, for example, have two degrees of freedom, i.e., polarity and chirality, and allow us to design an artificial magnetic lattice called “magnonic crystal” consisting of several magnetic vortices.
- Team Leader
- Hyun Soon Park
We study quantum phenomena in superconductors and magnetic materials. We are developing a measurement technology that enables us to observe, at high phase resolution, quantum phenomena at nanoscopic length scales.
