[HTML][HTML] Superconductivity in high-Tc and related strongly correlated systems from variational perspective: Beyond mean field theory

J Spałek, M Fidrysiak, M Zegrodnik, A Biborski - Physics Reports, 2022 - Elsevier
The principal purpose of this topical review is to single out some of the universal features of
high-temperature (high-T c) and related strongly-correlated systems, which can be …

We report high-resolution resonant inelastic x-ray scattering (RIXS) measurements of the
collective spin fluctuations in three compositions of the superconducting cuprate system La …

Unified theory of spin and charge excitations in high- cuprate superconductors: A quantitative comparison with experiment and interpretation

M Fidrysiak, J Spałek - Physical Review B, 2021 - APS
We provide a unified interpretation of both paramagnon and plasmon modes in high-T c
copper-oxides, and verify it quantitatively against available resonant inelastic x-ray …

Time-resolved resonant inelastic x-ray scattering in a pumped Mott insulator

Y Wang, Y Chen, C Jia, B Moritz, TP Devereaux - Physical Review B, 2020 - APS
Collective excitations contain rich information about photoinduced transient states in
correlated systems. In a Mott insulator, charge degrees of freedom are frozen, but can be …

Dynamical spin susceptibility in studied by resonant inelastic x-ray scattering

HC Robarts, M Garcia-Fernandez, J Li, A Nag… - Physical Review B, 2021 - APS
Resonant inelastic x-ray scattering (RIXS) is a powerful probe of elementary excitations in
solids. It is now widely applied to study magnetic excitations. However, its complex cross …
