no code implementations8 Jul 2020 Qiang Wei, Xuewei Zhang, Weiyin Deng, Jiuyang Lu, Xueqin Huang, Mou Yan, Gang Chen, Zhengyou Liu, Suotang Jia

Here we report the realization of a second-order topological Weyl semimetal in a 3D-printed acoustic crystal, which possesses Weyl points in 3D momentum space, 2D Fermi arc states on surfaces and 1D gapless states on hinges.
