Chiral Landau levels induced by two in-plane pseudomagnetic fields in underwater acoustic metamaterials
Jiao Shen, Zhiyong Chang, Xinzong Wang +6
The chiral zeroth Landau levels (LLs) constitute topologically protected bulk states that enable robust control of acoustic wave propagation. Given the central role of underwater a…
