Abstract:
The geometric-phase concept has far-reaching implications in many branches of physics 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14. The geometric phase that specifically characterizes the topological property of bulk bands in one-dimensional periodic systems is known as the Zak phase 15, 16. Recently, it has been found that topological notions can also characterize the topological phase of mechanical isostatic lattices 13. Here, we present a theoretical framework and two experimental methods to determine the Zak phase in a periodic acoustic system. We constructed a phononic crystal with … -
