The electronic structure and the phases of BaVS3
P. Fazekas, K. Penc, K. Radnoczi +8
BaVS3 is a moderately correlated d-electron system with a rich phase diagram. To construct the corresponding minimal electronic model, one has to decide which d-states are occupied…
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…
Gutzwiller variational theory for the Hubbard model with attractive interaction
Joerg Buenemann, Florian Gebhard, Katalin Radnoczi +1
We investigate the electronic and superconducting properties of a negative-U Hubbard model. For this purpose we evaluate a recently introduced variational theory based on Gutzwille…
