Comment on "Quantum Monte Carlo scheme for frustrated Heisenberg antiferromagnets"
K. S. D. Beach, Matthieu Mambrini, Fabien Alet
Quantum Monte Carlo methods are sophisticated numerical techniques for simulating interacting quantum systems. In some cases, however, they suffer from the notorious "sign problem"…
Hardcore dimer aspects of the SU(2) Singlet wavefunction
Matthieu Mambrini
We demonstrate that any SU(2) singlet wavefunction can be characterized by a set of Valence Bond occupation numbers, testing dimer presence/vacancy on pairs of sites. This genuine…
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…
Numerical Contractor Renormalization Method for Quantum Spin Models
Sylvain Capponi, Andreas Laeuchli, Matthieu Mambrini
We demonstrate the utility of the numerical Contractor Renormalization (CORE) method for quantum spin systems by studying one and two dimensional model cases. Our approach consists…
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…
LiVO(Si,Ge)O, a prototype of a two-dimensional frustrated quantum Heisenberg antiferromagnet
R. Melzi, P. Carretta, A. Lascialfari +4
NMR and magnetization measurements in LiVOSiO and LiVOGeO are reported. The analysis of the susceptibility shows that both compounds are two-dimensional Hei…
