Crystal-field splitting for low symmetry systems in ab initio calculations
S. V. Streltsov, A. S. Mylnikova, A. O. Shorikov +3
In the framework of the LDA+U approximation we propose the direct way of calculation of crystal-field excitation energy and apply it to La and Y titanates. The method developed can…
Spin-Isospin Model of NaV_2O_5
M. V. Mostovoy, J. Knoester, D. I. Khomskii
We argue that in the quarter-filled ladder compound NaV_2O_5 the quasi-one-dimensional spin system is strongly coupled to a low-energy antiferroelectric mode of the excitonic type.…
Spin and orbital excitations in magnetic insulators with Jahn-Teller ions
J. van den Brink, W. Stekelenburg, D. I. Khomskii +2
The elementary excitations of a model Hamiltonian that captures the low energy behavior of a simple two-fold degenerate Hubbard Hamiltonian with Hund's rule coupling, is studied. T…
