Quantum Effects and Broken Symmetries in Frustrated Antiferromagnets
Luca Capriotti
We investigate the interplay between frustration and zero-point quantum fluctuations in the ground state of the triangular and Heisenberg antiferromagnets, using finite…
Quantum Phase Transition in Coupled Spin Ladders
Luca Capriotti, Federico Becca
The ground state of an array of coupled, spin-half, antiferromagnetic ladders is studied using spin-wave theory, exact diagonalization (up to 36 sites) and quantum Monte Carlo tech…
Simulating Quantum Dissipation in Many-Body Systems
Luca Capriotti, Alessandro Cuccoli, Andrea Fubini +2
An efficient Path Integral Monte Carlo procedure is proposed to simulate the behavior of quantum many-body dissipative systems described within the framework of the influence funct…
Superconductivity in the two-dimensional t-J model
S. Sorella, G. B. Martins, F. Becca +4
Using computational techniques, it is shown that pairing is a robust property of hole doped antiferromagnetic (AF) insulators. In one dimension (1D) and for two-leg ladder systems,…
Stripes and spin-incommensurabilities are favored by lattice anisotropies
Federico Becca, Luca Capriotti, Sandro Sorella
Structural distortions in cuprate materials give a natural origin for anisotropies in electron properties. We study a modified one-band t-J model in which we allow for different ho…
Resonating Valence Bond Wave Functions for Strongly Frustrated Spin Systems
Luca Capriotti, Federico Becca, Alberto Parola +1
The Resonating Valence Bond (RVB) theory for two-dimensional quantum antiferromagnets is shown to be the correct paradigm for large enough ``quantum frustration''. This scenario, p…
