Non‐Hermitian (NH) physics describes novel phenomena in open systems that allow
generally complex spectra. Introducing NH physics into topological metamaterials, which …

Non-Hermiticity has recently emerged as a rapidly develo** field due to its exotic
characteristics related to open systems, where the dissipation plays a critical role. In the …

The first quantum fractal discovered in physics is the Hofstadter butterfly. It stems from large
external magnetic fields. We discover instead a class of non-Hermitian quantum fractals …

Recent studies have identified plasma as a topological material. Yet, these researches often
depict plasma as a fluid governed by electromagnetic fields, ie, a classical wave system …

Higher‐order topological insulators are a newly unveiled category of topological materials,
distinguished by their exceptional characteristics absent in conventional topological …

We introduce feedback-measurement technologies to achieve flexible control of Weyl points
and conduct the first experimental demonstration of Weyl type I-II transition in mechanical …

Three-dimensional topological semimetals have attracted tremendous attention across
multiple disciplines. Recently, a novel class of nodal-line semimetals hosting fourfold nodal …

One-dimensional (1D) π-d conjugated metal–organic frameworks (c-MOFs) have garnered
widespread research interest in chemical energy storage and conversion. In this work, we …

Non-Hermiticity alone can trigger topological phase transition in physical systems. Here, we
construct different unit cells in an acoustic Su Schrieffer Heeger chain with different …

Non-Hermitian Dirac point plays an important role in topological transition as their Hermitian
counterpart and connect non-Hermitian physics with band topology. Instead of being …
