When subjected to quasiperiodic driving protocols, superconducting systems have been
found to harbor robust time-quasiperiodic Majorana modes, extending the concept beyond …

Although topological band theory has been used to discover and classify a wide array of
novel topological phases in insulating and semimetal systems, it is not well suited to …

Recently, the study of topological structures in photonics has garnered significant interest, as
these systems can realize robust, nonreciprocal chiral edge states and cavity-like confined …

Topological metals are conducting materials with gapless band structures and nontrivial
edge-localized resonances. Their discovery has proven elusive because traditional …

We show that anomalous Floquet topological insulators generate intrinsic, non-Hermitian
topology on their boundaries. As a consequence, removing a boundary hopping from the …

Nonlinear topological insulators have garnered substantial recent attention as they have
both enabled the discovery of new physics due to interparticle interactions, and may have …

Photonic topological insulators exhibit bulk-boundary correspondence, which requires that
boundary-localized states appear at the interface formed between topologically distinct …

Over the last few years, crystalline topology has been used in photonic crystals to realize
edge-and corner-localized states that enhance light-matter interactions for potential device …

The search for strong topological phases in generic aperiodic materials and meta-materials
is now vigorously pursued by the condensed matter physics community. In this work, we first …

In the recent years, photonic Chern materials have attracted substantial interest as they
feature topological edge states that are robust against disorder, promising to realize defect …
