Evolution of the electronic structure in TaNiSe across the structural transition revealed by resonant inelastic x-ray scattering
Haiyu Lu, Matteo Ross, 1Jung-ho Kim +11
We utilized high-energy-resolution resonant inelastic X-ray scattering (RIXS) at both the Ta and Ni -edges to map out element-specific particle-hole excitations in TaNiSe$…
Orbital and Spin Character of Doped Carriers in Infinite-Layer Nickelates
M. Rossi, H. Lu, A. Nag +13
The recent discovery of superconductivity in NdSrNiO has drawn significant attention in the field. A key open question regards the evolution of the electronic str…
Evolution of spin excitations from bulk to monolayer FeSe
J. Pelliciari, S. Karakuzu, Q. Song +17
The discovery of enhanced superconductivity (SC) in FeSe films grown on SrTiO3 (FeSe/STO) has revitalized the field of Fe-based superconductors. In the ultrathin limit, the superco…
A pseudospinon continuum in CaIrO
Matteo Rossi, Pietro Marabotti, Yasuyuki Hirata +6
In so-called systems, including some iridates and ruthenates, the coherent superposition of orbitals in the ground state gives rise to hoppin…
Large polarons as key quasiparticles in SrTiO3 and SrTiO3-based heterostructures
Andrey Geondzhian, Alessia Sambri, Gabriella M. De Luca +11
Despite its simple structure and low degree of electronic correlation, SrTiO (STO) features collective phenomena linked to charge transport and, ultimately, superconductivity,…
Mobile orbitons in CaCuO: crucial role of the Hund's exchange
Roberto Fumagalli, Jonas Heverhagen, Davide Betto +9
We investigate the Cu edge resonant inelastic x-ray scattering (RIXS) spectra of a quasi-1D antiferromagnet CaCuO. In addition to the magnetic excitations, which are…
Resonant inelastic x-ray scattering of magnetic excitations under pressure
Matteo Rossi, Christian Henriquet, Jeroen Jacobs +15
Resonant inelastic x-ray scattering (RIXS) is an extremely valuable tool for the study of elementary, including magnetic, excitations in matter. Latest developments of this techniq…
Possibility to realize spin-orbit-induced correlated physics in iridium fluorides
M. Rossi, M. Retegan, C. Giacobbe +6
Recent theoretical predictions of "unprecedented proximity" of the electronic ground state of iridium fluorides to the SU(2) symmetric limit, relevant for su…
Long-range interactions in the effective low energy Hamiltonian of Sr2IrO4: a core level resonant inelastic x-ray scattering study
S. Agrestini, C. -Y. Kuo, M. Moretti Sala +12
We have investigated the electronic structure of Sr2IrO4 using core level resonant inelastic x-ray scattering. The experimental spectra can be well reproduced using ab initio densi…
Crystal field splitting in SrIrO ( = 1, 2) iridates probed by x-ray Raman spectroscopy
M. Moretti Sala, M. Rossi, A. Al-Zein +9
Non-resonant Raman spectroscopy in the hard X-ray regime has been used to explore the electronic structure of the first two members of the Ruddlesden-Popper series SrIr…
Orbital occupancies and the putative jeff = 1/2 groundstate in Ba2IrO4: a combined oxygen K edge XAS and RIXS study
M. Moretti Sala, M. Rossi, S. Boseggia +9
The nature of the electronic groundstate of Ba2IrO4 has been addressed using soft X-ray absorption and inelastic scattering techniques in the vicinity of the oxygen K edge. From th…
