Observation of heavy spin-orbit excitons propagating in a nonmagnetic background: The case of ( Ba , Sr ) 2 YIrO 6
We present a combined experimental and theoretical study of the elementary magnetic excitations in ${\mathrm{Ba}}_{2}{\mathrm{YIrO}}_{6}$ and ${\mathrm{Sr}}_{2}{\mathrm{YIrO}}_{6}$---the two mostExpand
Observation of spin-orbit excitations and Hund's multiplets in Ca2RuO4
We use Ru ${L}_{3}$-edge (2838.5 eV) resonant inelastic x-ray scattering (RIXS) to quantify the electronic structure of ${\mathrm{Ca}}_{2}{\mathrm{RuO}}_{4}$, a layered $4d$-electron compound thatExpand
Nontrivial Triplon Topology and Triplon Liquid in Kitaev-Heisenberg-type Excitonic Magnets.
TLDR
Mott insulators where on-site spin-orbit coupling favors a local J_{tot}=0 singlet ground state are discussed, and excitations into a low-lying triplet, triplons, are investigated and found to acquire nontrivial band topology in a magnetic field. Expand
Concept and realization of Kitaev quantum spin liquids
The Kitaev model is an exactly solvable S = 1/2 spin model on a 2D honeycomb lattice, in which the spins fractionalize into Majorana fermions and form a topological quantum spin liquid (QSL) in theExpand

Unraveling the Nature of Magnetism of the 5d^{4} Double Perovskite Ba_{2}YIrO_{6}.
TLDR
The data evidence that the magnetism of the studied material is solely due to a few percent of Ir^{4+} and Ir^{6+} magnetic defects while the regular Ir^{5+} sites remain nonmagnetic is reported. Expand
Correlated Quantum Phenomena in the Strong Spin-Orbit Regime
We discuss phenomena arising from the combined influence of electron correlation and spin-orbit coupling (SOC), with an emphasis on emergent quantum phases and transitions in heavy transition metalExpand
Highly frustrated magnetism in relativistic d4 Mott insulators: Bosonic analog of the Kitaev honeycomb model
We study the orbitally frustrated singlet-triplet models that emerge in the context of spin-orbit coupled Mott insulators with $t_{2g}^4$ electronic configuration. In these compounds, low-energyExpand
Strong Correlations from Hund’s Coupling
Strong electronic correlations are often associated with the proximity of a Mott-insulating state. In recent years however, it has become increasingly clear that the Hund’s rule couplingExpand
Collective nature of spin excitations in superconducting cuprates probed by resonant inelastic X-ray scattering.
TLDR
These findings demonstrate that the largest fraction of the spin-flip RIXS profiles in doped cuprates arises from magnetic collective modes, rather than from incoherent particle-hole excitations as recently suggested theoretically. Expand
