We were invited by the EIC of Europhys. Lett. for a Perspective paper on higher-order topological insulators. We wrote on the relation between Dirac cones and higher-order topological phases in quasi-continuous media (i.e., photonic and acoustic crystals). The paper entitled with "Dirac cones and ...

Abstract Gauge fields play a major role in understanding quantum effects. For example, gauge flux insertion into single unit cells is crucial towards detecting quantum phases and controlling quantum dynamics and classical waves. However, the potential of gauge fields in topological materia...

Jincheng and Rongqian got married! Congratulations to them! 

Abstract Topological phases of matter connect mathematical principles to real materials, and may shape future electronic and quantum technologies. So far, this discipline has mostly focused on single-gap topology described by topological invariants such as Chern numbers. Here, based on a t...

Abstract Most natural and artificial materials have crystalline structures from which abundant topological phases emerge1,2,3,4,5,6. However, the bulk–edge correspondence—which has been widely used in experiments to determine the band topology from edge properties—is inadequate in discerni...

Prof. Jian-Hua Jiang was awarded the NSFC distinguished young scientist funding (4 million RMB). Congratulations!
