Fingerprints of an Exotic Orbital-Selective Mott Phase in the Block Magnetic State of BaFeSe Ladders
Niravkumar D. Patel, Alberto Nocera, Gonzalo Alvarez +3
Resonant Inelastic X-Ray Scattering (RIXS) experiments on the iron-based ladder BaFeSe unveiled an unexpected two-peak structure associated with local orbital () excita…
Spin dynamics of the block orbital-selective Mott phase
J. Herbrych, N. Kaushal, A. Nocera +3
Iron-based superconductors display a variety of magnetic phases originating in the competition between electronic, orbital, and spin degrees of freedom. Previous theoretical invest…
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…
Doping evolution of charge and spin excitations in two-leg Hubbard ladders: comparing DMRG and RPA+FLEX results
A. Nocera, Y. Wang, N. D. Patel +4
We study the magnetic and charge dynamical response of a Hubbard model in a two-leg ladder geometry using the density matrix renormalization group (DMRG) method and the random phas…
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…
