Entangled spin-orbital phases in the bilayer Kugel-Khomskii model
Wojciech Brzezicki, Andrzej M. Oleś
We derive the Kugel-Khomskii spin-orbital (SO) model for a bilayer and investigate its phase diagram depending on Hund's exchange and the orbital splitting . In th…
Ferroelectricity from spin supercurrents in LiCuVO4
M. Mourigal, M. Enderle, R. K. Kremer +2
We have studied the magnetic structure of the ferroelectric frustrated spin-1/2 chain material LiCuVO4 in applied electric and magnetic fields using polarized neutrons. A symmetry…
Spin-orbital resonating valence bond liquid on a triangular lattice: Evidence from finite-cluster diagonalization
Jiří Chaloupka, Andrzej M. Oleś
We investigate the ground state of the spin-orbital model for triply degenerate orbitals on a triangular lattice which unifies intrinsic frustration of spin and orbi…
Spin exchange dominated by charge fluctuations of the Wigner lattice in the newly synthesized chain cuprate Na5Cu3O6
N. Zafar Ali, J. Sirker, J. Nuss +2
Na5Cu3O6, a new member of one dimensional charge ordered chain cuprates, was synthesized via the azide/nitrate route by reacting NaN3, NaNO3 and CuO. According to single crystal X-…
Quantum Criticality
Subir Sachdev, Bernhard Keimer
This is a review of the basic theoretical ideas of quantum criticality, and of their connection to numerous experiments on correlated electron compounds. A shortened, modified, and…
Ground State of the Quasi-1D \bvs\ resolved by Resonant Magnetic X-ray Scattering
Ph. Leininger, V. Ilakovac, Y. Joly +6
Resonant-magnetic x-ray scattering (RMXS) near the vanadium -absorption edges has been used to investigate the low temperature magnetic structure of high quality \bvs\ sin…
