Observation of Non-Hermitian Skin Dynamics in the Liouvillian Regime
Shu Yang, Yeyang Sun, Lingrui Hong +1
Open quantum systems generally do not perfectly preserve phase coherence: coupling to uncontrolled environments requires a density-matrix description based on the Liouvillian frame…
Observation of Floquet erratic non-Hermitian skin effect in photonic mesh lattice
Yeyang Sun, Shu Yang, Yi Yang
In ordered, translationally invariant non-Hermitian systems, the skin effect is understood as a boundary phenomenon: nonreciprocal hopping drives an extensive accumulation of eigen…
Photonic Floquet skin-topological effect
Yeyang Sun, Xiangrui Hou, Tuo Wan +4
Non-Hermitian skin effect and photonic topological edge states are of great interest in non-Hermitian physics and optics. However, the interplay between them is largly unexplored.…
Observation of acoustic spatiotemporal vortices
Hongliang Zhang, Yeyang Sun, Junyi Huang +4
Vortices in fluids and gases have piqued the interest of human for centuries. Development of classical-wave physics and quantum mechanics highlighted wave vortices characterized by…
Observation of squeezed Chern insulator in an acoustic fractal lattice
Junkai Li, Yeyang Sun, Qingyang Mo +2
Topological insulators are a new phase of matter with the distinctive characteristics of an insulating bulk and conducting edge states. Recent theories indicate there even exist to…
