Computing Resonant Inelastic X-Ray Scattering Spectra Using The Density Matrix Renormalization Group Method
A. Nocera, U. Kumar, N. Kaushal +3
We present a method for computing resonant inelastic x-ray scattering (RIXS) spectra in one-dimensional systems using the density matrix renormalization group (DMRG) method. By usi…

Multi-spinon and holon excitations probed by resonant inelastic x-ray scattering on doped one-dimensional antiferromagnets
Umesh Kumar, Alberto Nocera, Elbio Dagotto +1
Resonant inelastic x-ray scattering (RIXS) at the oxygen -edge has recently accessed multi-spinon excitations in the one-dimensional antiferromagnet (1D-AFM) \sco, where four-sp…

Direct observation of multi-spinon excitations outside of the two-spinon continuum in the antiferromagnetic spin chain cuprate Sr2CuO3
J. Schlappa, U. Kumar, K. J. Zhou +8
One-dimensional (1D) magnetic insulators have attracted significant interest as a platform for studying emergent phenomena such as quasiparticle fractionalization and quantum criti…
