Abstract Two-dimensional (2D) magnetism in van der Waals (vdW) atomic crystals and
moiré superlattices has emerged as a topic of tremendous interest in the fields of condensed …

Quantum spin liquids have been drawing much attention in recent years as a platform to
develop future quantum technologies, such as topological quantum computing. In particular …

This paper reviews the nature of two quasiparticles, the Majorana fermion and vison,
emergent in the Kitaev model, mainly from the theoretical point of view. We demonstrate how …

Motivated by reports of metallic behavior in the recently synthesized RuI3, in contrast to the
Mott-insulating nature of the actively discussed α-RuCl3, as well as RuBr3, we present a …

The layered RuBr3–RuI3 honeycomb structure solid solution was synthesized at high
pressures. The crystal structures are centrosymmetric (space group R) and based on …

Quantum spin Hall (QSH) insulators, with their unique helical edge states where
counterpropagating edge channels possess opposite spins, have attracted broad interest …

The recent synthesis of ruthenium trihalides Ru X 3 (X= Cl, Br, I) has enlarged the set of
material candidates for Kitaev spin liquids. The realization of the Kitaev model necessitates …

The present studies show that long-range magnetic order takes place in RuBr 3 at≈ 34 K.
The observations of clear oscillations in the muon time spectra demonstrate the presence of …

We investigate electronic properties of solid solution Ru (Br 1− x I x) 3 with honeycomb
structure which bridges the spin-orbit-entangled Mott insulator RuBr 3 and strongly electron …

Ru X 3 trihalides (X= halogen atoms) offer a prominent platform for exploring the Kitaev spin
liquid. Using polarization-resolved Raman spectroscopy, we report a comparative study of …
