Let there be light–to change the world we want to be! Over the past several decades, and
ever since the birth of the first laser, mankind has witnessed the development of the science …

The topological properties of an object, associated with an integer called the topological
invariant, are global features that cannot change continuously but only through abrupt …

The combination of broken Hermiticity and band topology in physical systems unveils a
novel bound state dubbed as the non-Hermitian skin effect (NHSE). Active control that …

Abstract Effects connected with the mathematical theory of knots emerge in many areas of
science, from physics, to biology. Recent theoretical work discovered that the braid group …

The nontrivial topological features in the energy band of non-Hermitian systems provide
promising pathways to achieve robust physical behaviors in classical or quantum open …

Thouless pumping provides one of the simplest manifestations of topology in quantum
systems and has attracted a lot of recent interest, both theoretically and experimentally …

Rapidly growing demands for fast information processing have launched a race for creating
compact and highly efficient optical devices that can reliably transmit signals without losses …

A hallmark feature of topological insulators is robust edge transport that is impervious to
scattering at defects and lattice disorder. We demonstrate a topological system, using a …

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 …

Topological photonics seeks to control the behaviour of the light through the design of
protected topological modes in photonic structures. While this approach originated from …
