Orbital order in degenerate Hubbard models : A variational study
Joerg Buenemann, Katalin Javorne-Radnoczi, Patrik Fazekas +1
We use the Gutzwiller variational many-body theory to investigate the stability of orbitally ordered states in a two-band Hubbard-model without spin degrees of freedom. Our results…
The emergence of Resonating Valence Bond physics in spin-orbital models
F. Mila, F. Vernay, A. Ralko +3
We discuss how orbital degeneracy, which is usually removed by a cooperative Jahn-Teller distortion, could under appropriate circumstances lead rather to a Resonating Valence Bond…
Quantum critical phase in BaVS
N. Barišić, I. Kézsmárki, P. Fazekas +4
We study the high-pressure metallic phase of high-purity single crystals of BaVS by measuring the temperature, pressure, and magnetic field dependence of the resistivity. Above…
Evidence of ferromagnetic quantum phase transition in BaSrVS
Andrea Gauzzi, Neven Barišic, Francesca Licci +5
Resistivity under pressure and magnetization measurements on BaSrVS single crystals with 0 0.18 and no sulphur deficiency show an abrupt onset of ferr…
Orbital order and spin-orbit coupling in BaVS3
Katalin Radnoczi, Patrik Fazekas
The correlated 3d sulphide BaVS3 undergoes a sequence of three symmetry breaking transitions which are reflected in the temperature dependence of the magnetic susceptibility, and i…
Sequence of multipolar transitions: Scenarios for URu2Si2
Patrik Fazekas, Annamaria Kiss, Katalin Radnoczi
d- and f-shells support a large number of local degrees of freedom: dipoles, quadrupoles, octupoles, hexadecapoles, etc. Usually, the ordering of any multipole component leaves the…
