Topological materials discovery has evolved at a rapid pace over the past 15 years following
the identification of the first nonmagnetic topological insulators (TIs), topological crystalline …

Higher-order topological insulators have been introduced in the precursory Benalcazar-
Bernevig-Hughes quadrupole model, but no electronic compound has been proposed to be …

The interplay between topology and interaction always plays an important role in condensed
matter physics and induces many exotic quantum phases, while rare transition metal layered …

Topological insulators offer significant potential to revolutionize diverse fields driven by
nontrivial manifestations of their topological electronic band structures. However, the …

The unique electronic and crystal structures driven by external pressure in transition metal
chalcogenides (TMCs) can host emergent quantum states. Here we report pressure-induced …

The opening of an energy gap in the electronic structure generally indicates the presence of
interactions. In materials with low carrier density and short screening length, long-range …

We report transport studies on the layered van der Waals topological crystalline insulator Ta
2 Pd 3 Te 5. The temperature-dependent resistance at high temperature is dominated by a …

Two-dimensional (2D) materials have gained lots of attention due to the potential
applications. In this work, we propose that based on first-principles calculations, the (2× 2) …

The helical edge states (ESs) protected by underlying Z 2 topology in two-dimensional
topological insulators (TIs) arouse upsurges in saturable absorptions thanks to the strong …

Layered Ta2M3Te5 (M= Pd, Ni) has emerged as a platform to study 2D topological
insulators, which have exotic properties such as spin-momentum locking and the presence …
