Magnetism of one-dimensional Wigner lattices and its impact on charge order
M. Daghofer, R. M. Noack, P. Horsch
The magnetic phase diagram of the quarter-filled generalized Wigner lattice with nearest- and next-nearest-neighbor hopping t_1 and t_2 is explored. We find a region at negative t_…

Spin-orbital entanglement near quantum phase transitions
Andrzej M. Oles, Peter Horsch, Giniyat Khaliullin
Spin-orbital entanglement in the ground state of a one-dimensional SU(2)SU(2) spin-orbital model is analyzed using exact diagonalization of finite chains. For spin…

One-dimensional orbital fluctuations and the exotic magnetic properties of YVO
Andrzej M. Oles, Peter Horsch, Giniyat Khaliullin
Starting from the Mott insulator picture for cubic vanadates, we derive and investigate the model of superexchange interactions between V ions, with nearly degenerate $t_{2g…
