Variational wave functions for frustrated magnetic models
Federico Becca, Luca Capriotti, Alberto Parola +1
Variational wave functions containing electronic pairing and suppressed charge fluctuations (i.e., projected BCS states) have been proposed as the paradigm for disordered magnetic…

Low temperature broken symmetry phases of spiral antiferromagnets
Luca Capriotti, Subir Sachdev
We study Heisenberg antiferromagnets with nearest- (J1) and third- (J3) neighbor exchange on the square lattice. In the limit of large spin S, there is a zero temperature (T) Lifsh…
