Effective hamiltonian approach and the lattice fixed node approximation
Sandro Sorella, Seiji Yunoki
We define a numerical scheme that allows to approximate a given Hamiltonian by an effective one, by requiring several constraints determined by exact properties of generic ''short…
From the triangular to the kagome lattice: Following the footprints of the ordered state
Liliana Arrachea, Luca Capriotti, Sandro Sorella
We study the spin-1/2 Heisenberg model in a lattice that interpolates between the triangular and the kagome lattices. The exchange interaction along the bonds of the kagome lattice…
Electron-hole asymmetry in magnetic properties of lightly doped high- superconductors: a quantum Monte Carlo study
S. Yunoki, S. Sorella
Using a recently developed variational quantum Monte Carlo method, magnetic properties of high- superconductors are studied at zero temperature (), by numerical simul…
A chiral spin liquid wave function and the Lieb-Schulz-Mattis theorem
S. Sorella, L. Capriotti, F. Becca +1
We study a chiral spin liquid wave function defined as a Gutwziller projected BCS state with a complex pairing function. After projection, spontaneous dimerization is found for any…
Geminal wavefunctions with Jastrow correlation: a first application to atoms
Michele Casula, Sandro Sorella
We introduce a simple generalization of the well known geminal wavefunction already applied in Quantum Chemistry to atoms and small molecules. The main feature of the proposed wave…
Suppression of Dimer Correlations in the Two-Dimensional - Heisenberg Model: an Exact Diagonalization Study
Luca Capriotti, Federico Becca, Alberto Parola +1
We present an exact diagonalization study of the ground state of the spin-half model. Dimer correlation functions and the susceptibility associated to the breaking of t…
