关键词:
摘要: We illustrate the concept of geometric phase in case two prototypical elastic systems, namely one-dimensional harmonic oscillator and a binary superlattice. demonstrate formally relationship between variation spectral wave number domains parallel transport vector field along paths on curved manifolds possessing helicoidal twists which exhibit non-conventional topology.
