All-dielectric metamaterials and metasurfaces have been demonstrated as ideal platforms to
manipulate electromagnetic waves and enhance light–matter interaction. Analogous to …

A review is given on the foundations and applications of non-Hermitian classical and
quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra …

Subwavelength optical resonators made of high-index dielectric materials provide efficient
ways to manipulate light at the nanoscale through mode interferences and enhancement of …

Exceptional points are spectral singularities in open quantum and wave systems that exhibit
a strong spectral response to perturbations. This feature can be exploited for a new …

The bulk-boundary correspondence is among the central issues of non-Hermitian
topological states. We show that a previously overlooked “non-Hermitian skin effect” …

While Hermiticity lies at the heart of quantum mechanics, recent experimental advances in
controlling dissipation have brought about unprecedented flexibility in engineering non …

Disorder, which qualitatively describes some measure of irregularities in spatial patterns, is
ubiquitous in many-body systems, equilibrium and non-equilibrium states of matter, network …

The relation between chiral edge modes and bulk Chern numbers of quantum Hall
insulators is a paradigmatic example of bulk-boundary correspondence. We show that the …

The quest towards the integration of ultra-fast, high-precision optical clocks is reflected in the
large number of high-impact papers on the topic published in the last few years. This interest …

Controlling the various degrees‐of‐freedom (DoFs) of structured light at both quantum and
classical levels is of paramount importance in optics. It is a conventional paradigm to treat …
