Multiple-magnon excitations shape the spin spectrum of cuprate parent compounds
Davide Betto, Roberto Fumagalli, Leonardo Martinelli +12
Thanks to high resolution and polarization analysis, resonant inelastic x-ray scattering (RIXS) magnetic spectra of La2CuO4, Sr2CuO2Cl2 and CaCuO2 reveal a rich set of properties o…
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…
Crystalline and magnetic structure of Ba2CuO3+δ investigated by x-ray absorption spectroscopy and resonant inelastic x-ray scattering
Roberto Fumagalli, Abhishek Nag, Stefano Agrestini +8
Motivated by the recent synthesis of BaCuO (BCO), a high temperature superconducting cuprate with putative ground state symmetry, we investigated its ele…
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…
Formation of Incommensurate Charge Density Waves in Cuprates
H. Miao, R. Fumagalli, M. Rossi +8
Although charge density waves (CDWs) are omnipresent in cuprate high-temperature superconductors, they occur at significantly different wavevectors, confounding efforts to understa…
