Acoustic spin-1 Weyl semimetal
Weiyin Deng, Xueqin Huang, Jiuyang Lu +4
Topological semimetal, hosting spin-1 Weyl point beyond Dirac and Weyl points, has attracted a great deal of attention. However, the spin-1 Weyl semimetal, which possesses exclusiv…
Acoustic spin-Chern insulator induced by synthetic spin-orbit coupling with spin conservation breaking
Weiyin Deng, Xueqin Huang, Jiuyang Lu +4
Topologically protected surface modes of classical waves hold the promise to enable a variety of applications ranging from robust transport of energy to reliable information proces…
Ideal type-II Weyl phase and topological transition in phononic crystals
Xueqin Huang, Jiuyang Lu, Feng Li +2
Ideal Weyl points, which are related by symmetry and thus reside at the same frequency, could promote the deep development and utilization of the Weyl physics. Although the ideal t…
Valley Topological Phases in Bilayer Sonic Crystals
Jiuyang Lu, Chunyin Qiu, Weiyin Deng +5
Recently, the topological physics in artificial crystals for classical waves has become an emerging research area. In this Letter, we propose a unique bilayer design of sonic cryst…
