In transition-metal compounds with partially filled 4 d and 5 d shells spin–orbit
entanglement, electronic correlations, and crystal-field effects conspire to give rise to a …

Fifteen years since its inception, the Kitaev model still boasts only a narrow group of material
realizations. The progress in studying and understanding one of them, lithium iridate Li 2 IrO …

Measurements of the magnetic Grüneisen parameter (Γ B) and specific heat on the Kitaev
material candidate α-RuCl 3 are used to access in-plane field and temperature dependence …

Two-dimensional coherent terahertz spectroscopy (2DCS) emerges as a valuable tool to
probe the nature, couplings, and lifetimes of excitations in quantum materials. It thus …

The pseudofermion functional renormalization group (PFFRG) method has proven to be a
powerful numerical approach to treat frustrated quantum spin systems. In its usual …

A Kitaev quantum spin liquid is a prime example of novel quantum magnetism of spin-orbit
entangled pseudospin-1/2 moments in a honeycomb lattice. Most candidate materials such …

Recent proposals for spin-1 Kitaev materials, such as honeycomb Ni oxides with heavy
elements of Bi and Sb, have shown that these compounds naturally give rise to …

Motivated by several claims of spin-orbit-driven spin-liquid physics in hexagonal Ba 3 Ti 3− x
Ir x O 9 hosting Ir 2 O 9 dimers, we report on resonant inelastic x-ray scattering (RIXS) at the …

Understanding the interplay between the inherent disorder and the correlated fluctuating-
spin ground state is a key element in the search for quantum spin liquids. H3LiIr2O6 is …

Owing to the availability of bright X-rays sources such as the ESRF-EBS, inelastic X-ray
scattering of samples contained in complex sample environments, including high pressure …
