Hidden Order in : The Need for a Dual Description
J. Mydosh, P. Chandra, P. Coleman +1
Motivated by experiment, we argue that the enigmatic hidden order in demands a dual description that encompasses both its itinerant and its local aspects. A combination…
Isospin model for suppression of charge order in hole- doped NaV_2O_5
P. Thalmeier
The layered perovskite compound NaV_2O_5 exhibits charge ordering (CO) and spin gap formation which is driven by inter- site Coulomb forces and exchange dimerisation. Experimentall…
Conductivity in quasi two-dimensional systems
Klaus Morawetz
The conductivity in quasi two-dimensional systems is calculated using the quantum kinetic equation. Linearizing the Lenard-Balescu collision integral with the extension to include…
Magnetic susceptibility in quasi one-dimensional Ba2V3O9: chain segmentation versus the staggered field effect
B. Schmidt, V. Yushankhai, L. Siurakshina +1
A pronounced Curie-like upturn of the magnetic susceptibility chi(T) of the quasi one-dimensional spin chain compound Ba2V3O9 has been found recently. Frequently this is taken as a…
Effective mass in quasi two-dimensional systems
Klaus Morawetz
The effective mass of the quasiparticle excitations in quasi two-dimensional systems is calculated analytically. It is shown that the effective mass increases sharply when the dens…
Quantum behavior of Orbitals in Ferromagnetic Titanates: Novel Orderings and Excitations
Giniyat Khaliullin, Satoshi Okamoto
We investigate the collective behavior of orbital angular momentum in the spin ferromagnetic state of a Mott insulator with orbital degeneracy. The frustrated nature of th…
