Flexible dimensional hierarchy of higher-order topology in the stacked Kagome-chain acoustic crystal
Abstract Manipulating wave propagation and energy collection plays a core role in modern physics, for which topological insulators hosting robust boundary states offer an ideal platform. However, there exist challenges in integrating multiple topological states like two-dimensional (2D) surface stat...
