Over the past decade, topology has emerged as a major branch in broad areas of physics,
from atomic lattices to condensed matter. In particular, topology has received significant …

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 has attracted increasing attention in recent years due to the unique
opportunities it provides to manipulate light in a robust way immune to disorder and defects …

Confining photons in a finite volume is highly desirable in modern photonic devices, such as
waveguides, lasers and cavities. Decades ago, this motivated the study and application of …

Surface plasmons (SPs) are electromagnetic surface waves that propagate at the interface
between a conductor and a dielectric. Due to their unique ability to concentrate light on two …

Terahertz science and technology promise many cutting-edge applications. Terahertz
surface plasmonic waves that propagate at metal–dielectric interfaces deliver a potentially …

Topological photonics is a rapidly emerging field of research in which geometrical and
topological ideas are exploited to design and control the behavior of light. Drawing …

In this Rapid Communication we predict several types of topological semimetals that exhibit
a bulk quadrupole moment. These semimetals are modeled with a three-dimensional …

Owing to the chirality of Weyl nodes, the Weyl systems can support one-way chiral zero
modes under a strong magnetic field, which leads to nonconservation of chiral currents—the …

Lattice thermal conductivity, κ L, is a fundamental parameter for evaluating the performance
of thermoelectric materials. However, the predicted value of κ L based on the Debye …
