Staggered-flux state for rectangular-lattice spin 1/2 Heisenberg antiferromagnet
N. E. Shaik, B. Dalla Piazza, D. A. Ivanov +1
We investigate the spin-1/2 Heisenberg model on a rectangular lattice, using the Gutzwiller projected variational wave function known as the staggered flux state. Using Monte Carlo…
Exact diagonalization study of the Hubbard-parametrized four-spin ring exchange model on a square lattice
C. B. Larsen, A. T. Rømer, S. Janas +5
We have used exact numerical diagonalization to study the excitation spectrum and the dynamic spin correlations in the next-next-nearest neighbor Heisenberg antiferromagnet…
Strain-Engineering Mott-Insulating LaCuO
O. Ivashko, M. Horio, W. Wan +15
The transition temperature of unconventional superconductivity is often tunable. For a monolayer of FeSe, for example, the sweet spot is uniquely bound to titanium-o…
Electronic and magnetic excitations in the "half-stuffed" Cu--O planes of BaCuOCl measured by resonant inelastic x-ray scattering
S. Fatale, C. G. Fatuzzo, P. Babkevich +11
We use resonant inelastic x-ray scattering (RIXS) at the Cu L edge to measure the charge and spin excitations in the "half-stuffed" Cu--O planes of the cuprate antiferromagnet…
- square lattice antiferromagnetism in the orbitally quenched insulator MoOPO
L. Yang, M. Jeong, P. Babkevich +12
We report magnetic and thermodynamic properties of a (Mo) magnetic insulator MoOPO single crystal, which realizes a - Heisenberg spin- model on a s…
Spin-Orbit-Induced Orbital Excitations in Sr2RuO4 and Ca2RuO4: A Resonant Inelastic X-ray Scattering Study
C. G. Fatuzzo, M. Dantz, S. Fatale +14
High-resolution resonant inelastic X-ray scattering (RIXS) at the oxygen K-edge has been used to study the orbital excitations of Ca2RuO4 and Sr2RuO4. In combination with linear di…
