Pattern Selection and Symmetry Competition in Materials Instabilities

摘要: One of the most natural and still intriguing behavior complex physico-chemical systems driven sufficiently far from thermal equilibrium is their ability to undergo symmetry-breaking instabilities leading spontaneous formation coherent structures over macroscopic time space scales (Nicolis Prigogine, 1977). Such a has been widely studied in various fields including physics, biophysics, chemistry materials science. The question why order appears spontaneously which patterns are selected among large manifold possibilities remains major theme experimental theoretical research (Swinney Gollub, 1981, Nicolis Baras, 1983, Hlavacek, 1985). Even though this was at first fundamental nature, it now more be technological importance.
