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 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…
Experimental Measurement of Non-Hermitian Left Eigenvectors
Xulong Wang, Guancong Ma
The duality of left and right eigenvectors underpins the comprehensive understanding of many physical phenomena. In Hermitian systems, left and right eigenvectors are simply Hermit…
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…
