Topological edge states have an important role in optical modulation with potential
applications in wavelength division multiplexers (WDMs). In this paper, 2D photonic crystals …

Topological semimetals have aroused great scientific interest due to their special properties
in materials science. Among the different types of topological semimetals, nodal surface …

The effect of Anderson diagonal disorder on the topological surface (drumhead) states of a
Weyl nodal loop semimetal (SM) is addressed. Since diagonal disorder breaks chiral …

The focus of topological materials has been recently expanded to metals and semimetals

We examined the high-pressure electronic structure of a single-component molecular
conductor [Pd (dddt) 2](dddt= 5, 6-dihydro-1, 4-dithiin-2, 3-dithiolate) at room temperature …

Topological band theory has emerged as a powerful framework to classify and understand
the electronic properties of materials. Topological semimetals, which have protected band …

Using first-principles density-functional theory calculations, we obtain the non-coplanar
nodal loop for a single-component molecular conductor [Pd (dddt) 2] consisting of HOMO …
