Acoustic realization of quadrupole topological insulators
Yajuan Qi, Chunyin Qiu, Meng Xiao +3
A quadrupole topological insulator, being one higher-order topological insulator with nontrivial quadrupole quantization, has been intensely investigated very recently. However, th…
Higher-order Dirac sonic crystals
Huahui Qiu, Meng Xiao, Fan Zhang +1
Discovering new topological phases of matter is a major theme in fundamental physics and materials science. Dirac semimetal provides an exceptional platform for exploring topologic…
Symmetry-enforced three-dimensional Dirac phononic crystals
Xiangxi Cai, Liping Ye, Chunyin Qiu +4
Dirac semimetals, the materials featured with discrete linearly crossing points (called Dirac points) between four bands, are critical states of topologically distinct phases. Such…
Observation of quadratic Weyl points and double-helicoid arcs
Hailong He, Chunyin Qiu, Xiangxi Cai +4
Very recently, novel quasiparticles beyond those mimicking the elementary high-energy particles such as Dirac and Weyl fermions have attracted great interest in condensed matter ph…
Polarity and spin-orbit coupling induced large interfacial exchange coupling an asymmetric charge transfer in iridate-manganite heterostructure
Tao Yu, Bei Deng, Liang Zhou +9
Charge transfer is of particular importance in manipulating the interface physics in transition-metal oxide heterostructures. In this work, we have fabricated epitaxial bilayers co…
Probing Weyl Physics with One-dimensional Sonic Crystals
Xiying Fan, Chunyin Qiu, Yuanyuan Shen +4
Recently, intense efforts have been devoted to realizing classical analogues of various topological phases of matter. In this Letter, we explore the intriguing Weyl physics by a si…
