Extended topological mode in a one-dimensional non-Hermitian acoustic crystal
Xulong Wang, Wei Wang, Guancong Ma
In Hermitian topological systems, topological modes (TMs) are bound to interfaces or defects of a lattice. Recent discoveries show that non-Hermitian effects can reshape the wavefu…
Observation of flat-band skin effect
Xulong Wang, Dongyi Wang, Congwei Lu +4
Symmetry-protected ideal flat bands in one-dimensional (1D) Hermitian lattices are populated by compact localized states (CLS) - a special class of localization with wavefunctions…
Topological phononics
Zeguo Chen, Tiantian Zhang, Xulong Wang +12
Topological phononics extends the foundational concepts of topological condensed matter physics to the realm of lattice vibrations and classical mechanical waves, unlocking robust,…
Exceptional deficiency of non-Hermitian systems
Zhen Li, Xulong Wang, Rundong Cai +5
Exceptional points (EPs) are non-Hermitian singularities associated with the coalescence of individual eigenvectors accompanied by the degeneracy of their complex energies. Here, w…
Experimental Realization of Special-Unitary Operations in Classical Mechanics by Nonadiabatic Evolutions
Congwei Lu, Xulong Wang, Guancong Ma
Artificial classical wave systems such as wave crystals and metamaterials have demonstrated promising capabilities in simulating a wide range of quantum mechanical phenomena. Yet s…
Topological Braiding of Bloch Eigenmodes Protected by Non-Abelian Quaternion Invariants
Xiao-Ming Wang, Jiaying Xu, Xulong Wang +2
Braiding has attracted significant attention in physics because of its important role in describing the fundamental exchange of particles. Infusing the braiding with topological pr…
