Demonstration of acoustic high-order Stiefel-Whitney semimetal in bilayer graphene sonic crystals
Xiao Xiang, Xiang Ni, Feng Gao +4
Recently, higher-order topological phases have endowed materials many exotic topological phases. For three-dimensional (3D) higher-order topologies, it hosts topologically protecte…
Chiral and non-chiral swift mode conversion near an exception point with dynamic adiabaticity engineering
Dong Wang, Wen-Xi Huang, Bo Zhou +7
The eigenvalue of a non-Hermitian Hamiltonian often forms a self-intersecting Riemann surface, leading to a unique mode conversion phenomenon when the Hamiltonian evolves along cer…
Acoustic mirror Chern insulator with projective parity-time symmetry
Xiao Xiang, Feng Gao, Yugui Peng +3
In condensed matter physics, symmetry profoundly governs the fundamentals of topological matter. The emergence of new topological phase is typically linked to the enrichment of sym…
Localized heat diffusion in topological thermal materials
Minghong Qi, Dong Wang, Pei-Chao Cao +4
Various unusual behaviors of artificial materials are governed by their topological properties, among which the edge state at the boundary of a photonic or phononic lattice has bee…
Reciprocity of thermal diffusion in time-modulated systems
Jiaxin Li, Ying Li, Pei-Chao Cao +6
The reciprocity principle governs the symmetry in transmission of electromagnetic and acoustic waves, as well as the diffusion of heat between two points in space, with important c…
Experimental Observation of Efficient Nonreciprocal Mode Transitions via Spatiotemporally-Modulated Acoustic Metamaterials
Zhaoxian Chen, Yugui Peng, Haoxiang Li +7
In lossless acoustic systems, mode transitions are always time-reversible, consistent with Lorentz reciprocity, giving rise to symmetric sound manipulation in space-time. To overco…
