Charge response function probed by resonant inelastic x-ray scattering: the signature of electronic gaps of YBaCuO

Giacomo Merzoni, Leonardo Martinelli, Lucio Braicovich +6

In strongly correlated systems the complete determination of the dynamical susceptibility is of special relevance because of the entwinement of the spin and char…

Electronic excitations in J=0 Os halides studied by RIXS and optical spectroscopy

P. Warzanowski, M. Magnaterra, P. Stein +10

We demonstrate that the cubic antifluorite-type halides KOsCl, KOsBr, and RbOsBr are excellent realizations of non-magnetic J=0 compounds. The magnetic susc…

Collective nature of orbital excitations in layered cuprates in the absence of apical oxygens

Leonardo Martinelli, Krzysztof Wohlfeld, Jonathan Pelliciari +19

We have investigated the 3d orbital excitations in CaCuO2 (CCO), Nd2CuO4 (NCO), and La2CuO4 (LCO) using high-resolution resonant inelastic x-ray scattering. In LCO they behave as w…

Absence of localized electrons in KTaO interface superconductors

Xinqiang Cai, Jungho Kim, Leonardo Martinelli +19

Recently, an exciting discovery of orientation-dependent superconductivity was made in two-dimensional electron gas (2DEG) at the interfaces of LaAlO/KTaO (LAO/KTO) or EuO/…

RIXS observation of bond-directional nearest-neighbor excitations in the Kitaev material NaIrO

M. Magnaterra, K. Hopfer, Ch. J. Sahle +13

Spin-orbit coupling locks spin direction and spatial orientation and generates, in semi-classical magnets, a local spin easy-axis and associated ordering. Quantum spin-1/2's defy t…

RIXS interferometry and the role of disorder in the quantum magnet BaTiIrO

M. Magnaterra, M. Moretti Sala, G. Monaco +8

Motivated by several claims of spin-orbit driven spin-liquid physics in hexagonal BaTiIrO hosting Ir2O9 dimers, we report on resonant inelastic x-ray scattering…
