Pseudospin Hall Transport Induced by Berry Curvature
Qinhui Jiang, Jidong Song, Qingyang Mo +4
Pseudospin-1 Dirac systems exhibit unique physics distinct from conventional Dirac cones, such as flat-band crossings and non-Abelian characteristics, yet their topological transpo…
Universal Quantized Berry-Dipole Flat Bands
Qingyang Mo, Shuang Zhang
Perfectly flat bands with nontrivial quantum geometry have emerged as a frontier for exotic topological phenomena and superconductors. Here, we unveil a universal family of quantiz…
Demonstration of returning Thouless pump in a Berry dipole system
Qingyang Mo, Shanjun Liang, Xiangke Lan +2
The Thouless pump, a cornerstone of topological physics, enables unidirectional quantized wave/particle transport via geometric Berry phase engineering in periodically driven syste…
Tensor-monopole-induced topological boundary effects in four-dimensional acoustic metamaterials
Qingyang Mo, Shanjun Liang, Cuicui Lu +2
Gauge field theory provides the mathematical and conceptual framework to describe and understand topological singularities such as Weyl points and magnetic monopoles. While singula…
Observation of oriented Landau levels in Berry dipole semimetals
Qingyang Mo, Riyi Zheng, Cuicui Lu +3
Band crossing points, such as Weyl and Dirac points, play a crucial role in the topological classification of materials and guide the exploration of exotic topological phases. The…
Higher-order topological phase in an acoustic fractal lattice
Junkai Li, Qingyang Mo, Jian-Hua Jiang +1
Higher-order topological insulators, which support lower-dimensional topological boundary states than the first-order topological insulators, have been intensely investigated in th…
Observation of squeezed Chern insulator in an acoustic fractal lattice
Junkai Li, Yeyang Sun, Qingyang Mo +2
Topological insulators are a new phase of matter with the distinctive characteristics of an insulating bulk and conducting edge states. Recent theories indicate there even exist to…
