Ising phases of Heisenberg ladders in a magnetic field
Karlo Penc, Jean-Baptiste Fouet, Shin Miyahara +2
We examine the influence of weak anisotropic interactions on the T=0 phase diagram of the frustrated two-leg Heisenberg ladder, a well-studied spin model exhibiting integer and fra…
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…
Doped Singlet-Pair Crystal in the Hubbard model on the checkerboard lattice
Didier Poilblanc, Karlo Penc, Nic Shannon
In the limit of large nearest--neighbor and on--site Coulomb repulsions, the Hubbard model on the planar pyrochlore lattice maps, near quarter-filling, onto a doped quantum fully p…
Local density of states and Friedel oscillations around a non-magnetic impurity in unconventional density wave
Andras Vanyolos, Balazs Dora, Attila Virosztek
We present a mean-field theoretical study on the effect of a single non-magnetic impurity in quasi-one dimensional unconventional density wave. The local scattering potential is tr…
