Name : 23rd Symposium on Liquid Crystals
Number : 23
Location : [in Japanese]
Date : September 25, 1997 - September 27, 1997
We propose a question; " If liquid crystal phase intrinsically possesses characteristics of machinery, then how it behaves? We postulate that liquid crystal phases are mechanical rotor's systems consist of molecular rotors. We have proposed a melting model; A resonance between molecular vibration mode and rotational mode is take place at certain temperature and it induces melting and transition to the existing phase to another phase. We have examined phase transition behaviors as rotor based on mechanical dynamics of rigid and elastic rotors. External and internal damping effects are examined and interpreted in relation to molecular structural characteristics.
