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…
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…
Massive coherent equipartition of light by the geometric phase of null space
Xiangrui Hou, Dongyi Wang, Fangyu Wang +3
Light source is a foundational to photonic science and technology. However, a significant challenge remains in generating and distributing coherent light from a single on-chip sour…
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…
Interplay between disorder and topology in Thouless pumping on a superconducting quantum processor
Yu Liu, Yu-Ran Zhang, Yun-Hao Shi +24
Topological phases are robust against weak perturbations, but break down when disorder becomes sufficiently strong. However, moderate disorder can also induce topologically nontriv…
