| Outline of Final Research Achievements |
Using the unique scanning-probe techniques, in the non-equilibrium quantum Hall regime, we found the spatial correlation between the electron scattering region from the one-dimensional spin-polarized edge channel and the nuclear spin polarization region. Furthermore, a similar correlation was found in quantum point contacts that form a one-dimensional electron system. These results provide microscopic pictures of one-dimensional hyperfine interaction between the electron and nuclear spins that induces the intriguing phenomenon in the non-equilibrium quantum Hall regime.
