Exciton-assisted low-energy magnetic excitations in a photoexcited Mott insulator on a square lattice by Kenji Tsutsui, Kazuya Shinjo, Shigetoshi Sota, Takami Tohyama

“…Time-resolved spectroscopies at ultrafast timescales are a powerful tool for understanding the properties of a Mott insulator on a square lattice. Here, the authors theoretically investigate the transient magnetic dynamics in a photoexcited half-filled Hubbard model and identify an increase in the two magnon weight of the Raman scattering as an exciton-assisted magnetic excitation.…”

Origin of the exciton mass in the frustrated Mott insulator Na[subscript 2 ]IrO[subscript 3] by Cao, Gang, Alpichshev, Zhanybek, Sie, Edbert Jarvis, Mahmood, Fahad, Gedik, Nuh

“…We use a three-pulse ultrafast optical spectroscopy to study the relaxation processes in a frustrated Mott insulator Na[subscript 2]IrO[subscript 3]. By being able to independently produce the out-of-equilibrium bound states (excitons) of doublons and holons with the first pulse and suppress the underlying antiferromagnetic order with the second one, we were able to elucidate the relaxation mechanism of quasiparticles in this system. …”

Proposal for detecting spin-chirality terms in Mott insulators via resonant inelastic x-ray scattering by Lee, Patrick A., Ko, Wing Ho

“…We consider the question of whether resonant inelastic x-ray scattering (RIXS) can be used to detect many-body excitations that are coupled to the spin-chirality terms S[subscript i]·(S[subscript j]×S[subscript k]) in a Mott insulator. We find that while the spin-chirality terms are in general absent in the usual experimental setups of RIXS, there are prospects of realizing such terms if one considers instead the scattering near a pre-edge. …”
