Spin order, spin excitations, and RIXS spectra of spin-1/2 tetramer chains

Junli Li, Jun-Qing Cheng, Trinanjan Datta +1

We investigate the spin dynamics of a 1D spin-1/2 Heisenberg tetramer chain. Employing a combination of Density Matrix Renormalization Group, quantum renormalization group, and per…

RIXS Identification of Optical Phonon-Spin Coupling Effects in CrSBr

Jayajeewana N. Ranhili, Chamini S. Pathiraja, Brody Brogdon +11

Resonant inelastic x-ray scattering provides experimental signatures of spin-phonon coupling in CrSBr through temperature-dependent Cr $L$ -edge spectra. Low-energy excitations are…

Multimagnon and multispinon $L_{3}$ -edge RIXS spectra of an effective $J ~_{1} - J ~_{2} - J ~_{3}$ square lattice Heisenberg model

Kai-Yuan Qi, Shangjian Jin, Trinanjan Datta +1

We investigate the multimagnon and the multispinon $L_{3}$ -edge resonant inelastic x-ray scattering (RIXS) spectra of a spin-1/2 effective $J ~_{1} - J ~_{2} - J ~_{3}$ squar…

Magnetically modified double slit based x-ray interferometry

S. Atkar, Z. Tumbleson, S. A. Morley +7

We demonstrate an experimental approach to determine magneto-optical effects which combines x-ray magnetic circular dichroism (XMCD) with x-ray interferometry, based on the concept…
