  • Non-Hermitian physics extends criticality beyond conventional Hermitian systems. Here, the authors report a universal many-body critical skin effect arising from the interplay of multiple pumping channels and interactions, revealing new collective edge phenomena and real-to-complex transitions.

  • In vivo surface-enhanced Raman scattering (SERS) imaging allows non-invasive visualization of tumours for biomedical applications. Here, the authors report porous cubic AuAg alloy nanoshells exhibiting plasmonic properties and porosity-dependant SERS in the second window of the near-infrared for in vivo tumour detection.

  • Quantized response has so far eluded classical system beyond linear response theory. Here, the authors predict that a quantized classical response, arising from fundamental mathematical properties of the Green’s function, shows up in steady-state response of a non-Hermitian system without invoking a linear response theory.

  • In non-Hermitian systems, fundamental concepts like bandgaps and locality cannot be applied as in Hermitian systems. Here, the authors introduce a class of non-Hermitian critical scenarios where the eigenstates and energies jump discontinuously across a critical point, with anomalous scaling properties

  • Anyons are a general class of particles with unusual statistics beyond conventional bosons and fermions. In this work, the authors reveal that anyonic statistics can profoundly affect the non-Hermitian skin effect (NHSE) dynamically, suppressing or even reversing the NHSE-induced unidirectional evolution of both state dynamics and quantum information spreading, while keeping qualitatively the same skin-localization of static eigensolutions.

  • PT-symmetric non-Hermitian systems possess real and complex eigenenergies in the symmetry unbroken and broken phases, respectively. Based on these spectral features and non-Hermitian band theory, the authors provide a framework to generate localized states and dynamics at different sectors of non-Hermitian systems, which can be selectively activated/deactivated by breaking/restoring PT symmetry.

  • Non-Hermitian physics describes an open system, which is susceptible to loss or gain and has been recently used to demonstrate unusual physical phenomena in non-trivial topological systems. Here, the authors investigate the physics of impurity effects in non-Hermitian, non-reciprocal lattices and discuss how the results can be realised using an electrical circuit.

  • Although characterizing the Seifert surface is central to the realization of novel phases in topological materials, this has been a purely mathematical construction so far. This paper proposes an experimentally realistic scheme for the realization and imaging of 4D-embedded Seifert surfaces, opening up a way for experimental topological characterization
