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 …

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 …

Nanophotonics offers opportunities for engineering and exploiting the quantum properties of
light by integrating quantum emitters into nanostructures, and offering reliable paths to …

Entanglement and topology portray nature at the fundamental level but differently. Entangled
states of particles are intrinsically sensitive to the environment, whereas the topological …

Metasurfaces are subwavelength structured thin films consisting of arrays of units that allow
the control of polarization, phase, and amplitude of light over a subwavelength thickness …

Waveguide lattices offer a compact and stable platform for a range of applications, including
quantum walks, condensed matter system simulation, and classical and quantum …

Topological insulators feature a number of topologically protected boundary modes linked to
the value of their bulk invariant. While in one-dimensional systems the boundary modes are …

On-chip topological nanophotonic devices, which take photons as information carriers with
topological protection during light propagation, have great application potential in the next …
