| Outline of Final Research Achievements |
Shear flow can change not only the structure of soft matter but also the nature of fluctuation and response by breaking the time-reversal symmetry. We constructed a system combining a rheometer and a confocal laser scanning microscope to mainly observe non-equilibrium structures and fluctuations under shear flow. We successfully observed anomalous fluctuation and response in nematic liquid crystal and colloidal systems, which are brought about by non-conservative forces characteristic to non-equilibrium systems. As for the liquid crystal, we analyzed the results in terms of the Ericksen-Leslie theory and furthermore derived a modified fluctuation-dissipation relation.
