Magnetism and superconductivity of strongly correlated electrons on the triangular lattice
Cédric Weber, Andreas Laeuchli, Frédéric Mila +1
We investigate the phase diagram of the \tj Model on a triangular lattice using a Variational Monte-Carlo approach. We use an extended set of Gutzwiller projected fermionic trial w…
Frustrated three-leg spin tubes: from spin 1/2 with chirality to spin 3/2
J. -B. Fouet, A. Laeuchli, S. Pilgram +2
Motivated by the recent discovery of the spin tube [(CuCltachH)Cl]Cl, we investigate the properties of a frustrated three-leg spin tube with antiferromagnetic intra-rin…
Spinon deconfinement in doped frustrated quantum antiferromagnets
Didier Poilblanc, Andreas Laeuchli, Matthieu Mambrini +1
The confinement of a spinon liberated by doping two-dimensional frustrated quantum antiferromagnets with a non-magnetic impurity or a mobile hole is investigated. For a static vaca…
Interacting classical dimers on the square lattice
Fabien Alet, Jesper Lykke Jacobsen, Gregoire Misguich +3
We study a model of close-packed dimers on the square lattice with a nearest neighbor interaction between parallel dimers. This model corresponds to the classical limit of quantum…
Strain induced correlation gaps in carbon nanotubes
T. A. Gloor, F. Mila
We calculate the change in the correlation gap of armchair carbon nanotubes with uniaxial elastic strain. We predict that such a stretching will enlarge the correlation gap for all…
Quantum Phase Transition in the SU(4) Spin-Orbital Model on the Triangular Lattice
Karlo Penc, Matthieu Mambrini, Patrik Fazekas +1
Motivated by the absence of cooperative Jahn-Teller effect in LiNiO2 and BaVS3, two layered oxides with triangular planes, we study the SU(4) symmetric spin-orbital model on the tr…
