Resolving the Orbital Character of Low-energy Excitations in Mott Insulator with Intermediate Spin-orbit Coupling

K. von Arx, P. Rothenbühler, Qisi Wang +10

Multi-band Mott insulators with moderate spin-orbit and Hund's coupling are key reference points for theoretical concept developments of correlated electron systems. The ruthenate…

Magnon interactions in a moderately correlated Mott insulator

Qisi Wang, S. Mustafi, E. Fogh +20

Quantum fluctuations in low-dimensional systems and near quantum phase transitions have significant influences on material properties. Yet, it is difficult to experimentally gauge…

High-Temperature Charge-Stripe Correlations in La $_{1.675}$ Eu $_{0.2}$ Sr $_{0.125}$ CuO $_{4}$

Qisi Wang, M. Horio, K. von Arx +24

We use resonant inelastic x-ray scattering to investigate charge-stripe correlations in La $_{1.675}$ Eu $_{0.2}$ Sr $_{0.125}$ CuO $_{4}$ . By differentiating elastic from inelastic scatter…
