Constraints on the two-dimensional pseudo-spin 1/2 Mott insulator description of SrIrO
Berend Zwartsenberg, Ryan P. Day, Elia Razzoli +10
SrIrO has often been described via a simple, one-band pseudo-spin 1/2 model, subject to electron-electron interactions, on a square lattice, fostering analogies with cu…
Nuclear probes of an out-of-equilibrium plasma at the highest compression
G. Zhang, M. Huang, A. Bonasera +20
We report the highest compression reached in laboratory plasmas using eight laser beams, E12 kJ, =2 ns in third harmonic on a CD target at the She…
The Fermi surface of Sr2RuO4: spin-orbit and anisotropic Coulomb interaction effects
Guoren Zhang, Evgeny Gorelov, Esmaeel Sarvestani +1
The topology of the Fermi surface of Sr2RuO4 is well described by local-density approximation calculations with spin-orbit interaction, but the relative size of its different sheet…
Importance of exchange-anisotropy and superexchange for the spin-state transitions in LnCoO3 (Ln=La,Y,RE) cobaltates
Guoren Zhang, Evgeny Gorelov, Erik Koch +1
Spin-state transitions are the hallmark of rare-earth cobaltates. In order to understand them, it is essential to identify all relevant parameters which shift the energy balance be…
Orbital-order melting in rare-earth manganites: the role of super-exchange
Andreas Flesch, Guoren Zhang, Erik Koch +1
We study the mechanism of orbital-order melting observed at temperature T_OO in the series of rare-earth manganites. We find that many-body super-exchange yields a transition-tempe…
Ab initio study of the giant ferroelectric distortion and pressure induced spin-state transition in BiCoO3
Ting Jia, Hua Wu, Guoren Zhang +4
Using configuration-state-constrained electronic structure calculations based on the generalized gradient approximation plus Hubbard U method, we sought the origin of the giant tet…
Modulation of the thermodynamic, kinetic and magnetic properties of the hydrogen monomer on graphene by charge doping
Liang Feng Huang, Mei Yan Ni, Guo Ren Zhang +4
The thermodynamic, kinetic and magnetic properties of the hydrogen monomer on doped graphene layers were studied by ab initio simulations. Electron doping was found to heighten the…
The spin states of Co ions in La1.5Ca0.5CoO4 from first-principles
Ting Jia, Hua Wu, Guoren Zhang +4
The spin states and electronic structure of layered perovskite La1.5Ca0.5CoO4 are investigated using fullpotential linearized augmented plane-wave method. All the computational res…
KAgF3: quasi-one-dimensional magnetism in three-dimensional magnetic ions sublattice
Xiaoli Zhang, Guoren Zhang, Ting Jia +3
The electronic structure and magnetic properties of the Jahn-Teller-distorted perovskite KAgF3 have been investigated using the full-potential linerized aug- mented plane-wave meth…
Orbitally relieved magnetic frustration in NaVO2
Ting Jia, Guoren Zhang, Zhi Zeng +1
The magnetic properties of NaVO2 are investigated using full-potential linearized augmented plane wave method. We perform calculations for three structures. For the rhombohedral st…
