Advances in high-resolution and spin-resolved scanning tunnelling microscopy, as well as
atomic-scale manipulation, have enabled the bottom-up, atom-by-atom creation and …

Surfaces are at the frontier of every known solid. They provide versatile supports for
functional nanostructures and mediate essential physicochemical processes. Intimately …

Topological phases of matter have attracted much attention over the years. Motivated by
analogy with photonic lattices, here we examine the edge states of a one-dimensional trimer …

The band structure and electronic properties of a material are defined by the sort of
elements, the atomic registry in the crystal, the dimensions, the presence of spin–orbit …

The fabrication of atomically precise structures with designer electronic properties is one of
the emerging topics in condensed matter physics. The required level of structural control can …

Kinks, point‐like geometrical defects along dislocations, domain walls, and DNA, are stable
and mobile, as solutions of a sine‐Gordon wave equation. While they are widely …

Topological mechanical metamaterials have been widely explored for their boundary states,
which can be robustly isolated or transported in a controlled manner. However, such …

Many-body interactions give rise to the appearance of exotic phases in Hermitian physics.
Despite their importance, many-body effects remain an open problem in non-Hermitian …

We propose a scheme to simulate the extended Su-Schrieffer-Heeger (SSH) model by using
the hybrid cavity magnonics system. We consider a hybrid cavity-magnon array with N sites …

Certain lattices with specific geometries have one or more spectral bands that are strictly flat,
ie, the electron energy is independent of the momentum. This can occur robustly irrespective …
