Evolution of the magnetic excitations in electron-doped
X. T. Li, S. J. Tu, L. Chaix +13
We investigated the high energy spin excitations in electron-doped , a cuprate superconductor, by resonant inelastic x-ray scatter…
Antiferromagnetic Excitonic Insulator State in Sr3Ir2O7
D. G. Mazzone, Y. Shen, H. Suwa +13
Excitonic insulators are usually considered to form via the condensation of a soft charge mode of bound electron-hole pairs. This, however, presumes that the soft exciton is of spi…
Single laser pulse driven thermal limit of the quasi-two dimensional magnetic ordering in SrIrO
Ruitang Wang, J. Sun, D. Meyers +10
Upon femtosecond-laser stimulation, generally materials are expected to recover back to their thermal-equilibrium conditions, with only a few exceptions reported. Here we demonstra…
Ultrafast dynamics of spin and orbital correlations in quantum materials: an energy- and momentum-resolved perspective
Y. Cao, D. G. Mazzone, D. Meyers +4
Many remarkable properties of quantum materials emerge from states with intricate coupling between the charge, spin and orbital degrees of freedom. Ultrafast photo-excitations of t…
Direct detection of dimer orbitals in BaAlIrO
Y. Wang, Ruitang Wang, Jungho Kim +7
The electronic states of many Mott insulators, including iridates, are often conceptualized in terms of localized atomic states such as the famous " state". Altho…
On the possibility to detect multipolar order in URuSi by the electric quadrupolar transition of resonant elastic X-ray scattering
