Mapping the unoccupied state dispersions in TaNiSe with resonant inelastic x-ray scattering
C. Monney, M. Herzog, A. Pulkkinen +8
The transition metal chalcogenide TaNiSe undergoes a second-order phase transition at K involving a small lattice distortion. Below , a band gap at the cente…
Novel Cu-based dz2 order at a YBa2Cu3O7/ manganite interface
Roxana Gaina, Christopher W. Nicholson, Maxime Rumo +12
The interplay of nearly degenerate orders in quantum materials can lead to a myriad of emergent phases. A prominent case is that of the high-Tc cuprates for which the relationship…
Anisotropic magnetic excitations and incipient Néel order in Ba(FeMn)As
Fernando A. Garcia, Oleh Ivashko, Daniel E. McNally +7
It is currently understood that high temperature superconductivity (SC) in the transition metal substituted iron arsenides Ba(Fe)As is promoted b…
Orbital breathing effects in the computation of x-ray d-ion spectra in solids by ab initio wave-function-based methods
Nikolay A. Bogdanov, Valentina Bisogni, Roberto Kraus +8
In existing theoretical approaches to core-level excitations of transition-metal ions in solids relaxation and polarization effects due to the inner core hole are often ignored or…
Probing inter- and intrachain Zhang-Rice excitons in LiCuO and determining their binding energy
Claude Monney, Valentina Bisogni, Ke-Jin Zhou +8
Cuprate materials, like those hosting high temperature superconductivity, represent a famous class of materials where the correlations between the strongly entangled charges and sp…
Electron-lattice interactions strongly renormalize the charge transfer energy in the spin-chain cuprate LiCuO
Steve Johnston, Claude Monney, Valentina Bisogni +9
Strongly correlated insulators are broadly divided into two classes: Mott-Hubbard insulators, where the insulating gap is driven by the Coulomb repulsion on the transition-meta…
Orbital control of effective dimensionality: from spin-orbital fractionalization to confinement in the anisotropic ladder system CaCu2O3
Valentina Bisogni, Krzysztof Wohlfeld, Satoshi Nishimoto +11
Fractionalization of an electronic quasiparticle into spin, charge and orbital parts is a fundamental and characteristic property of interacting electrons in one dimension. However…
Femtosecond dynamics of magnetic excitations from resonant inelastic x-ray scattering in CaCu2O3
Valentina Bisogni, Stefanos Kourtis, Claude Monney +10
Taking spinon excitations in the quantum antiferromagnet CaCu2O3 as an example, we demonstrate that femtosecond dynamics of magnetic excitations can be probed by direct resonant in…
High-energy magnetic excitations in BiSrCaCuO: Towards a unified description of the electronic and magnetic degrees of freedom in the cuprates
M. P. M. Dean, A. J. A. James, R. S. Springell +10
We investigate the high-energy magnetic excitation spectrum of the high- cuprate superconductor BiSrCaCuO (Bi-2212) using Cu edge resonant inelastic…
Determining the Short-Range Spin Correlations in Cuprate Chain Materials with Resonant Inelastic X-ray Scattering
Claude Monney, Valentina Bisogni, Ke Jin Zhou +13
We report a high-resolution resonant inelastic soft x-ray scattering study of the quantum magnetic spin-chain materials Li2CuO2 and CuGeO3. By tuning the incoming photon energy to…
Spin excitations in a single LaCuO layer
M. P. M. Dean, R. S. Springell, C. Monney +9
The dynamics of S=1/2 quantum spins on a 2D square lattice lie at the heart of the mystery of the cuprates \cite{Hayden2004,Vignolle2007,Li2010,LeTacon2011,Coldea2001,Headings2010,…
Three-Dimensional Fermiology by Soft-X-Ray ARPES: Origin of Charge Density Waves in VSe2
Vladimir N. Strocov, Ming Shi, Masaki Kobayashi +7
Electronic structure of crystalline materials is their fundamental characteristic which is the basis of almost all their physical and chemical properties. Angle-resolved photoemiss…
