The resonating valence bond wave functions in quantum antiferromagnets
Alberto Parola, Sandro Sorella, Federico Becca +1
Projected-BCS wave functions have been proposed as the paradigm for the understanding of disordered spin states (spin liquids). Here we investigate the properties of these wave fun…

Projected BCS Wave Functions for Low Dimensional Frustrated Spin Systems
Luca Capriotti, Federico Becca, Alberto Parola +1
Twenty-five years after the first proposal, the question whether the ground state of a frustrated spin-half system is well described by a spin-liquid Resonating Valence Bond (RVB)…
