Chirality is an indispensable concept that pervades fundamental science and nature,
manifesting itself in diverse forms, eg, quasiparticles, and crystal structures. Of particular …

Three-dimensional obstructed atomic insulators (OAIs) are characterized by the appearance
of floating surface states (FSSs) at specific surfaces. Benefiting from this feature, our study …

We compute the ground-state properties of fully polarized, trapped, one-dimensional
fermionic systems interacting through a Gaussian potential. We use an antisymmetric …

Based on first-principles calculations, we demonstrate that 1H/2H-phase transition metal
dichalcogenides MX 2 (M= Nb, Ta; X= S, Se, Te) are unconventional metals, which have an …

Topological materials with boundary (surface/edge/hinge) states have attracted tremendous
research interest. Additionally, unconventional (obstructed atomic) materials have recently …

Introducing the concept of topology has revolutionized materials classification, leading to the
discovery of topological insulators and Dirac–Weyl semimetals,–. One of the most …

We study the coupling between topological bands and two distinct magnetic sublattices in
EuMn 1− x Zn x Sb 2 (0≤ x≤ 1) using a combination of magnetotransport measurements …

We investigate the topological properties of the helical atomic chains occurring in elemental
selenium and tellurium. We postulate a realistic model that includes spin-orbit interaction …

By systematic theoretical calculations, we have revealed an excitonic insulator (EI) in a van
der Waals layered compound $\rm {Ta_ {2} Pd_ {3} Te_5} $. First-principles calculations …

Based on the elementary band representations (EBR), many topologically trivial materials
are classified as unconventional ones (obstructed atomic limit), where the EBR …
