| Research Abstract |
We have studied various frictional phenomena at interface and in bulk by theoretical, numerical and experimental technique. It turned out that atomically clean surface, which is one of the most simple frictional systems, shows various novel phenomena related to the structure of the system. Lubrication layer of nanoscale also shows similar behavior. It is well known that the size distribution of earthquake shows power law. We demonstrated that the model experiment using granular systems reproduces the power law under certain condition. The numerical simulation based on phenomenological model shows that the size distribution depends on the size of the system and the deviation from the power law grows for larger systems.
